Saxophone player's (original song) mix mastering Under the influence of the corona, it is natural for musicians who are unable to perform live activities and who are in a nest to go to songwriting. During this period, the number of requests for mix mastering of home-recorded songs from musicians who are usually active mainly in live performances increased for this service, which handles sound quality improvement services. Due to the service strategy, we specialize in restoration-type audio editing such as noise removal and audio restoration, but the range of defense that can be supported by audio and video is extremely wide. We do not accept on-site recording, but since we were aiming to be a recording engineer in the first place, we can also handle mix mastering of various musical works. Songs that helped mix mastering Live performance + sequence track up one grade If you can't record at the same time in a band style, recording at home using a DAW is probably the most efficient way to create music. Except for the main part of live recording such as vocals and saxophone, it can be said that the mainstream production method with the highest cost performance is to type in with a sequencer or make a track with sampling material. The major DAW software Cubase and Logic are equipped with software sound sources that can be used by professional musicians as they are, and the quality is also higher than in the MIDI era when external sound sources were heavily used. However, even with such a sound source, long experience, expertise, and other skills are required to mix it so that it can be sublimated to the next dimension. Sometimes only self-recording instruments are cheap Due to the quality of the software instruments and sample materials, and the lack of quality of the main tracks such as vocals recorded by themselves, it is not uncommon for only the leading part to feel cheap. The quality of live musical instruments and vocal parts can be greatly improved by just using the compressor. This service supports such mixed problems at an affordable price. Of course, it is possible to mix or request restoration of only the main tracks, not the entire song. Cleans up noise mixed in at home recording Noise is always a problem when recording at home. Even if the sound is clear, a highly sensitive condenser microphone will pick up even the small sound of the hands of the clock. In addition, useless room reverb is added, and it is difficult to make clear recordings as it should be. If the arrangement of the orchestra is lively, you may not be concerned about the small noise. However, the compressor or limiter may make the noise more noticeable, or the tone may look strange. With hybrid sound reform, even severe sound sources are converted into clear tracks that are easy to mix. Depending on the degree, it also supports a wide range of repairs for sound cracking and other voice problems. Negative recording material will also be raised to studio quality. We provide mix and mastering that can withstand distribution releases at high cost performance. Please feel free to contact us.

We accept requests for removal / reduction from those who are having trouble with the rubbing noise of the IC recorder. I'm Yamakawa, a sound reformer who works on repairing, improving, and removing noise from voice data. Removal / reduction of cloth rubbing noise is a relatively frequently consulted matter. When recording with the IC recorder smartphone in your pocket The microphone and cloth rub against each other and make a strong noise, making it difficult to hear important conversations. Recently, there is an increasing need to try to record conversation content as evidence for fighting in court, such as power harassment, sexual harassment, and contract cancellation interviews. It is difficult for important keywords at the time of a dispute to be drowned out by such noise, and if it is frequent, it may be difficult to request translation (transcription) because it is jarring. Cloth rubbing noise can be significantly reduced The latest voice restoration technology (audio restoration) can easily reduce or eliminate the rubbing noise. If it is recorded at a certain conversation volume, the removal accuracy is high. However, it is not possible to restore the "drown voice" component that does not exist in the recorded data. The above video sample is a recording under a high-level recording environment such as a movie. Most of the noise of the IC recorder sound source that we handle on a daily basis is even worse. In Hybrid Sound Reform, we receive hundreds of requests for improvement of IC recorder recording noise removal and voice restoration from general users every year. Please contact us by all means.

Can't you hear the contents of the lecture wearing a mask because the microphone sound is muffled? I'm Yamakawa, who runs a sound quality improvement service for video and audio data. A new lifestyle due to the corona sickness has taken root, and a mask is indispensable when going out. Since the fall of 2020, the number of inquiries has been increasing at the same time as the event events have been gradually activated. "If you talk with a microphone while wearing a mask, your voice will be muffled and difficult to hear." I'm worried. In the exchange between President Trump and the media, while wearing a masked reporter with Ichamon "You are clear and easy to ask questions without a mask," he praised (laughs). Obviously, wearing a mask makes the sound muffled and makes it difficult to hear people's voices. Hearing is different between the scene and after recording the video Microphones are used for lectures in large venues so that the audience can hear them. Even if you think that it is a little difficult to hear if you wear a mask on the spot, there are many cases where you can not hear what you are talking about when you record and preview it. Recording only with a camera microphone without line recording from the microphone adds the following negative factors. Reverberation of the venue Ventilation opens windows and doors Noise from outside the venue related to 2 (car engine noise, etc.) When these are added, the audio state becomes a level that makes little sense for recording. It can be said to be fatal when recording a professional lecture where the content of the talk is the center of value. Jet noise + microphone performance leaking from another booth The other day, the case you requested was a small lecture held at a large exhibition hall booth that included all of the above negative factors. Because the venue is close to the airport, in addition to the harsh environment with the noise of jet planes passing by, The flashy microphone performance of the next booth was mixed in, and the voice of the performer who was muffled (depending on the angle of view) was defeated by the voice of another booth, and it was in a very difficult state. ・ Overall noise reduction ・ Boost by distinguishing only human voice ・ Cut and reduce the voice of the next booth Execute improvement processing centering on the above work. After presenting the sample, it was adopted and delivered safely. For those who are having trouble with "difficult-to-listen audio / video data" even for projects that are not related to masks Please feel free to contact Hybrid Sound Reform if you come.

Zoom Webinar archived video echo mitigation request I'm Yamakawa @HSR_YB, a hybrid sound reformer who works on repairing and improving voice data. Since the Corona disaster, remote appearances on TV programs have become a standard, but we often see broadcasts that are difficult to hear due to interruptions in sound due to problems such as radio wave conditions. ZOOM, a web conferencing system, has become firmly established in corporate internal meetings. Since those call records can be recorded, they can be used not only for meetings but also for in-house training and online seminars. The number of cases where it is secondarily used as a teaching material as a video archive is increasing. Difficult to hear the audio of the video archive Such video archives are caused by unexpected audio problems due to communication environment and equipment setting mistakes, and the number of consultations for this service is increasing. The sound is interrupted The voice echoes Delay (mountain phenomenon) is applied The noise is terrible The sound is quiet The above is the main content of the voice troubles that were consulted regarding 2020 ZOOM. In some cases, some problems were combined. Echo reduction for specific performers One of the requests for sound quality improvement was a ZOOM dialogue with four performers who were supposed to use it for e-learning materials. The three performers had clear voices on the microphone, but only one performed a strong echo. The viewer has a strong sense of discomfort. With our audio restoration technology, reverberation can be reduced to some extent. When recording with a voice recorder in the audience seats of the lecture hall, we have delivered many times to the problem that the reverberant sound is too loud and it is difficult to hear the contents. This time, only one subject has a wave in the echo condition depending on the location. It was a rather troublesome task to apply mitigation processing to each part that felt uncomfortable and to bring the sound quality of the other three people as close as possible. When we presented an improvement sample, it was evaluated that the discomfort was considerably reduced, and it was officially adopted. Difficult to reduce delay (mountain phenomenon) AAA class It is said that a delay (mountain phenomenon) has occurred endlessly for 90 minutes in the main voice recorded in the lecture. There was also a consultation. There is also a complete give-up case depending on the degree. "Ah ~ (Ah ~) Today ~ (Today ~)" Such a state. It was a very uncomfortable and harsh condition that the next word was covered by the previous word. We often refuse such situations, but we will make full use of the "specific sound erasing technology" that our service has to find out if we can somehow reduce it due to the fact that we have presented a slightly expensive budget. I considered it. As in the sample video above, it is relatively easy (if the number of processes is small) to erase the sound that is clearly not mixed with other sounds such as "pee" in the live venue. However, when the performer's voice is overwhelmed by his own voice, it is difficult to determine where the echo sound is mixed, and it is not an exaggeration to say that it is the number one among the many sound quality improvements made last year. It was. I worked all day for about 7 days and was able to deliver it. We will take care of such difficult problems if your budget matches. We also offer free diagnosis (sample creation). If you would like to improve ZOOM-related voice troubles and noise, please feel free to contact us for hybrid sound reform.

Important academic societies and lectures that require transliteration. I think there are many people who record the contents with a voice recorder. The other day, I received a consultation that the microphone in the venue was so loud that I could hardly hear the recorded content. It seems that clients always use voice recorders when attending conferences. In order to avoid the risk of recording failure, we also recorded voice memos on the iPhone as well as a dedicated voice recorder at the same time. He asked us to present two types of files to this service and clear one of them. The problem that the performer's voice echoes too much in a large space The recorded sound source was certainly hard to hear as it was. The voice of the performer echoed in the large venue. These improvements are not the ones with a high probability of being adopted through trials, but are difficult projects. The point of improving such a sound source is ① Suppress ambient noise ② Reduce only reverberation ③ Emphasize the voice of the performer ④ Overall sound pressure increase The above is the main subject, but if the reverberation component is extremely removed, the balance of the sound will be significantly lost, and it will often be difficult to hear, especially in the case of a speaking human voice. In addition, the sound that is difficult to hear is that the performer's voice echoes in the venue like a "warn", so even if the reverberation component is reduced, the echo will still be emphasized when raising the performer's voice. It's easy to go around in a dignified manner. Therefore, it is difficult to present an improved sound source that nods the client unless (1) to (4) are processed in an exquisite balance. Why this improvement worked The sound source this time had a low-frequency "goo" sound mixed in with the "(1) ambient noise" component for a long time, so the biggest thing was that removing these sound improved the sound of the performer's voice. It's a success factor. We couldn't reduce the reverberation component so much, but we were able to capture what we were talking about, so we decided to use it safely. Since this is a relatively difficult project, there is no guarantee that it will succeed, but if you have a problem with an "inaudible sound source" even though you must translate it, please feel free to contact us. You can try it for free with the sound source you actually want to improve. It was Yamakawa, a sound former of hybrid sound reform that operates a service that clears voice memos. #ボイスメモ #ボイスレコーダー #録音アプリ #響いて聞こえない #文字起こし #反訳作業 #音声クリア化

This service started when I heard the sound of old VHS at the Live music club where I appeared and thought "What's this?" Recently, we have been working on a wide range of sound quality corrections such as sound adjustment of movies, voice restoration of video production companies, clarification of voice recorders, etc., but even now half of the users are high level music activities in earnest. Musician. Why can we call it high level? Of course, that's because it's an artist who can provide attractive songs and performances even if they are played and recorded in one live performance. I personally like songs that have been written with automation and DAW edited for all effects, but live recordings are sometimes more realistic and inspiring than intentionally recorded records. Was there no howling mixed in the live sound source? After a free trial, we helped create a full album with only live recordings. Howling was mixed in the main song, which is the representative song of the band. Can this be removed? It was from the consultation. The band, which consists of vocals, acoustic guitar, and violin + chorus, produced very groovy and comfortable songs even in a style without a rhythm section. The howling in question is not a state in which the vocalist goes in front of the speaker and becomes a blatant "pee", but a thin howling of about 5 to 10 seconds at random points. Chain with the white ball of the guitar. I imagine that the cause is that the environment on the stage is changing due to play. The lyrics aren't strong enough to be drowned out, but it's a level that even an amateur can tell, "Oh, howling." It was a rather difficult sound source to release as a finished product sound source. Howling is clearly heard as a "foreign body" in the surrounding sounds. It can be clearly identified by the spectrogram meter (a meter that visualizes the sound components) of the application called RX that we use for editing. Sometimes it's very difficult to find a sound that doesn't know where it blends in and is confused, but if you can identify the location, you can locally reduce the volume or blend it into the surrounding sounds to make it almost unnoticeable. I will. Proposals for mastering live sound sources "It's amazing! Then can you make corrections like ✖✖?" It became an exchange with the musician who used it, and it was a little mistake part, another howling sound source, an air recording sound source with a little environmental noise. After receiving many requests such as noise elimination, it ended up being a full album with more than 13 songs. I've had users buy their skills, but I think it's a big reason that I proposed not only so-called "noise elimination and correction" but also live mastering that adds value to the song. I will. Unlike multi-recorded sound sources, if individual instruments and microphones are not recorded in para, in many cases the instrument balance will be a little unbalanced. With sound sources recorded in the air at a live house, noise in the audience seats is still annoying, and even if you add mastering sound pressure, they will be emphasized. It is also a fact that there is a big difference from the quality of live sound sources released by professionals on DVDs. As I mentioned at the beginning of the blog, the reason why I started the service was that the old VHS sound source that I appeared in was too much. Cheap sound → It's too different from the sound you actually experienced live Audio restoration (voice restoration technology) using a spectrogram meter is a new technology under development that is less than 10 years old. There is almost no technical difference with a well-known veteran engineer. In addition, we have been actively working on sound sources with severe recording conditions not only for professionals but also for general users, so it can be said that only the restoration experience value is top class in Japan. (Top engineers do not receive such troublesome and unprofitable work) There are quite a lot of repeaters because they feel the value of enjoying their own performances with good sound. The fusion of the above techniques with the latest mastering can dramatically increase the value of the live recording (which can be difficult, of course). "I want you to enjoy live performances with professional-class sound quality!" We will continue to propose hybrid live sound sources without changing such aspirations. We will not compromise on technical research for that purpose. We look forward to a free trial from a band that has absolute confidence in their live performance.

The other day, a client who handles a lot of video content of a certain genre requested to remove audio noise. The whole video was uniformly mixed with a rather terrible "boom" audio noise. Imagine that there was a problem with the plug connection, etc. due to a problem with the equipment. If a video cameraman who also records audio brings a linear PCM recorder to the sub unit, or if there is a problem recording two microphones, a gun microphone (both are mono) and a built-in microphone of the camera, on different channels. It seems that there are many cases where it is recorded with insurance. Even so, in simple shooting with a single unmanned fixed camera, there are times when only one audio is recorded without assuming such trouble. For professional creators, voice troubles in such cases can be said to be a serious mistake of losing the next job. At first glance, there are many cases where even a sound source in a terrible state, "this may not be possible", can be improved when recording with professional equipment. We delivered it to our client safely. Most professional sound quality improvements cover serious mistakes, so it's annoying that we can't easily publish improvement samples. You can make a trial order of "Trouble sound source in trouble" by hybrid sound reform. It is also widely used by professional video production companies and freelance video photographers. Please feel free to try it. We accept sound adjustment, restoration, and noise removal of video content. #Recording mistake #Equipment trouble #Voice noise #Video production

Noise removal and remastering of classical concerts I'm Yamakawa @HSR_YB, a sound reformer. Recently, I have received repeated orders for noise removal from classical music enthusiasts' private sound sources. There are various sound source sources, such as old TV recordings such as VTRs, FM air checks, and those recorded in the audience seats of concerts, with the promise that the client will enjoy them for personal use. In classical music, various conductors and orchestras perform timeless masterpieces, so even the same songs have different interpretations and playing styles. Therefore, it seems that your favorite performance may not be a CD that is on the market. Broadcast archive sound source noise Broadcast sound sources were originally stored in videos and tapes, and now they are enjoying playback by converting them to digital files. The first request was for a consultation that the radio noise that had been mixed in the high frequency range called "pee" could not be removed. For listeners who want to immerse themselves in the performance that they feel is the best, even a slight "pee" noise is annoying. The pitch of the beeping sound is clear and stable, so if it is not so loud, it can be removed cleanly in most cases. After removing this cleanly, I started to request it repeatedly. Noise removal from audience recordings is a Hardwork The most recent work I received was a sound source that recorded the concert that the client himself went to in the audience. If you use a linear PCM recorder and can record in a good place, you may be able to enjoy some music. However, it was difficult to record in the audience seats, and it was located near the customers who made noise with bad etiquette. Anxious noises such as clearing throat and stepping have been mixed in most parts of the performance. Classical concerts have a large dynamic range and are very delicate. Removing them is not easy. Above all, the creaking sound of the chair, which was mixed many times during the delicate violin solo, was in the AA class of noise removal difficulty. Even the latest technology cannot handle these noises automatically. "Gi" "ri" "ri" of the chair It is necessary to finely pinpoint each note. It is a fine edit just like a painting restoration. .. Also supports mastering to adjust how to pull out the instrument This client also received a request for overall sound quality adjustment. Despite the violin concerto, the leading solo violin sounds cloudy. It was also a factor that the bass range was strong due to the recording position, but we also performed remastering with exquisite equalizing adjustment and saturation. Estimate of sound source with high repair difficulty and long length Many full orchestra symphonies and concertos have a long playing time. Therefore, when the noise processing of the difficulty level AA class takes a small hour, a daunting task is waiting. Therefore, the estimate is expensive, and casual orders may be difficult unless you are a wealthy person and a maniac. If you have an important sound source that you really want to repair and listen to in a beautiful state even if it costs money, please contact us. You can order after receiving the actual sound source and listening to the improvement effect.
