Clearly improved air conditioning sound (air conditioner) mixed in video / audio data

There are also seasonal requests for sound quality improvement services. Because the air conditioner is operating full-time in the office in the summer, I get used to the sound of the air conditioner, and the staff working in the office do not care. However, when recording audio and video in that environment, if you do not choose the recording location with consideration for the air outlet, the recorded audio data will contain more noise from the air conditioner (air conditioning) than expected.


 The other day, I received a request to reduce the air conditioner noise mixed in such voice data. If the purpose of voice is voice memo, it is easy to give up some noise as "unavoidable", but I still want to consider it when sharing the conversation content with many people.

The site operates a very convenient service that reforms such audio (including video) data that says "I would be happy if it could be improved ."

Features of audio data shared with a large number of people and listening environment

The example you requested was a recording of the deliberation in the evaluation of a certain practical test. The voice data recorded in stereo with the voice recorder had a good conversation volume level, but I was having trouble with the mixed sound of the air conditioner.

In recent years, there are many smartphone users, and it is possible to easily record such voice data.

Easy to share with many people. Smartphones have a high probability of listening on earphones, and noise often makes it harder to hear than expected.

Free software noise processing cannot handle

It is a little difficult to remove these noises. Since the air conditioner is a sound that is continuously emitted by mixing the artificial fans, motors, and wind sounds of the machine, it is good to turn down the volume at the part where the conversation is interrupted, but it reduces the sound of the talking voice. Still requires special software.

It can be said that it is difficult to improve the air-conditioning sound during conversation with the noise canceller built into the voice recorder and the noise effector that can be done with free software. This site utilizes software called RX-6 Advanced from iZotope of the United States, which incorporates the latest voice correction technology . The part where only the air conditioner is used is profiled (analyzed), and those components are subtracted from the original data.

I do not assert that it can be improved 100%. So free trial

Of course, it cannot be said that it can be improved 100% depending on the recording condition. Therefore, there are few companies that provide such services for general users. If you can't improve even if you work for a huge amount of time, it will not lead to sales. Therefore, some companies offer diagnostic fees just to determine if they can be improved.

This service is free for trial. Although it is an excerpt, we will actually take care of the sound source that is troubled by noise and perform improvement processing. Of course, there are a certain number of cases where it cannot be improved and it is canceled, but we keep the technical level high by handling many cases even for voices that are difficult to repair , such as "This is impossible".

Satisfied with the noise reduction of the air conditioner, delivered safely
