Frequently Asked Questions
- What bitrate should I choose to compress audio?
- 128kbps for voice recordings and podcasts, 192kbps for music listening, and 320kbps if you want maximum quality with smaller file size than WAV. Lower bitrate = smaller file but noticeable quality drop below 128kbps.

- Up to 80% smaller depending on the original format and target bitrate. A 50 MB WAV file at 128kbps becomes around 5 MB. The actual reduction varies based on audio length and content.

- The tool supports MP3, WAV, M4A, and OGG files as input. The output is always a compressed MP3 file, which works on all devices and platforms.
- Will audio compression affect the listening experience?
