Improved sound quality of voice recorders, IC recorders, voice memo apps for smartphones, and video data. The state-of-the-art audio restoration technology is generously introduced.

Basic charge

Estimate method based on work man-hour points (P) 35P / 1,840 yen

We will actually take the "sound source file you want to improve clearly" from the user and consider the most effective improvement recipe. Create a partial audio sample that has actually been improved (free of charge) . At that point, the work man-hour points are counted and the estimated amount is presented. You will be asked to decide whether or not to hire.

Concept of pricing

It is not easy to clearly improve the hard-to-hear data recorded by general users.

In most cases, various processes are performed in a complex manner. There are many cases where even if a professional professional performs complicated processing, it cannot be improved. (Recruitment rate from estimate is 50-60%)

If you can improve only a little even if you spend a lot of processing man-hours, the offered price does not meet the user's expected improvement value. In order to avoid such problems, Hybrid Sound Reform estimates in advance samples, work man-hours, improvement level and delivery date.

Basically non-compliant for files longer than 3 hours

Hidden camera sound sources such as 8 to 10 hours are not supported. In the case of video, it is possible to visually grasp the scene where a person appears, but in principle it takes a huge amount of work to confirm the location where "sound is contained" in an audio file with poor sound quality, and we refuse it in principle. ..

If the requesting user confirms all the recorded contents and then can specify the improvement time zone in detail, we will respond if the conditions are met, so please contact us. Please check the service policy for other detailed terms of use.
