Sound @ Reformer

Actual communication when requesting noise removal for self-recording (when supporting musicians)

I visited the website and contacted you to request the use of the noise reduction service. The sound source is a 3 minute 20 second piano solo (wav / 24bit96k) recorded with a zoom IC recorder.

In addition, can you tell me the procedure for using the service?

I would like to check the sound source once. Please upload your request data to a storage service such as Google Drive or Gigafile, and send us the link.

At that time, I would appreciate it if you could supplement the part where you feel the problem. (If you have difficulty uploading, you can mail an SD card etc.)

We will present a test reform sound source for about 1 minute. We will make an estimate according to the editing man-hours (labor) and improvement level.

If it is difficult to repair with our technology, we may give up there. If you listen to the test sound source and it does not exceed the expected value requested by the user, you can cancel it without worrying about it.

If you feel the benefits of the estimated price, we would like you to pay the fee by bank transfer or credit card, and proceed with the flow of finishing the rest of the remodeling.

Since the piano solo is very delicate, it takes a lot of skill to finish it naturally and it may not meet your expectations, but we will aim for the best possible condition.

After uploading the data, we will check it immediately and start the test reform work. Please experience the test reform. Nice to meet you.

We will send you the sound source file via iCloud. Please check before removing noise. The sound source was recorded at XX Piano Studio YY store 2Bst. We are recording in XY microphone mode using SONY's linear PCM recorder. For the microphone setting, open the top lid of the upright piano, extend the boom stand straight from the back of the piano chair, and aim straight down from a height of about 10 cm from the top lid toward the inside of the piano. The main parts that I would like you to arrange are as follows.

1. Overall hiss noise

2. Noise at the following points 0:02 0:03 0:04 0:17 2:03

It would be nice if pedal noise and nail noise could be eliminated, but if there were, I felt that the freshness would resonate with my heart, so I think this is sufficient. Similarly, leave the 3:20 recording stop noise.

We intend to distribute and sell the processed file as it is, but we do not need reverb or mastering because we want you to enjoy the goodness of no makeup.

Immediately, I did a test reform. 0: 02/0: 03/0: 04 We have removed the above 3 points of noise and the entire hiss noise.

Please download it from here and listen to it. ▲ (* Link like this)

Since the noise of the piano solo is removed, the point of processing is to reduce the noise without any discomfort. If you erase it completely, you will feel like "cutting and pasting", so we interpret it as "fitting into the performance".

At 0:03 and 0:04, it's almost natural, but at 0:02, a small ghost-like sound remains. Probably, it is assumed that this kind of ghost will appear even when processing 0:17. In order to drive further, it is necessary to try several patterns of processing approaches, and it takes more than double the man-hours, so we would like to discuss the delivery date and estimate.

We have uploaded 3 files.

① 1st_fixed.wav (3-point noise processing only)

② NS-1.wav (his noise processing, thin to the limit)

③ NS2.wav (His noise is thinly cut in two steps)

Hiss noise cut analyzes the noise component of the silent part at the beginning and removes a specific component from the overall performance. Due to the nature, the larger the shaving width, the more the feeling of air tends to be impaired, and the timbre of the acoustic instrument changes significantly, and some users may not be satisfied with even a little processing.

We will present two versions of hiss noise cut level as a guide for the level of scraping. Of course, it is easy to raise the cut level.

Man-hour points 30

Improvement level B +

Remodeling fee 1,300 yen + consumption tax

I hurriedly provided a sample and a quote. If you wish to process the rest, we will inform you of the transfer destination and other information separately. If you have a request for finishing, we will do our best to accommodate it.

Please consider it. Thank you.

We have confirmed the sample and quotation. As you explained, the result of NS2 was the most familiar to me from the interpretation of "fitting into the performance". Please use this method for the rest of the processing. Please also contact us regarding payment methods.


This is an example of communication with users (actually email). After the exchange continued, we received a request for the mastering 2 version.

Although it depends on the congestion situation, we will propose specific treatment after careful hearing. You can use it with confidence even for first-time users and beginners.

We aim to be the No. 1 cospa for audio restoration with a simple estimate.

Environmental noise in the video If you want to reduce the engine noise of a motorcycle or car

In addition to engine sounds and announcements of sound trucks that you want to turn off from voice, we also support a wide range of applications such as wind blowing, rubbing microphones and clothes, noise, clip noise due to volume over, noise removal due to equipment troubles and radio interference.


Is the microphone echoing and hard to hear? Academic society voice recorder sound source

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.


Removal of wind noise in onboard interviews

"I interviewed a fisherman on board." I received a consultation as usual to reduce the wind noise mixed in the video cut, and received a free trial .


Removes mobile phone radio noise mixed in band performance (with improvement sample)

When recording a performance with a linear PCM recorder, there seems to be a case where the recorded data gets quite terrible noise if the iPhone is nearby. It is not the noise of the environmental sound of the audience seats picked up by the so-called microphone, but the very strong noise that destroys the audio data itself.

We have worked to reduce unpleasant noise that interferes with the recorded performance.
