Someone already solved a similar problem?

After a series of experiments came to the conclusion that it is better to write with the maximum quality (frequency, bitrate), and after processing to compress back to 8000/8, then the sound of the highest quality remains. - Brandy_OHara53 commented on October 3rd 19 at 04:38
