How it helps
Use audio compressor on the go
Audio compression is useful when a recording is too large to upload, email, or send by chat. Lower bitrate and mono output can make speech files smaller.
The compressor creates a new MP3 at the selected bitrate. For speech, 64–128 kbps is often enough. For music, use a higher bitrate.
