Audio tools FAQ
Are these audio tools free?
Yes. No sign-up, no watermark and no daily limit.
What MP3 bitrate should I pick?
128 kbps is fine for speech, 192 kbps for most music, and 320 kbps for the best MP3 quality.
Does converting to MP3 lose quality?
MP3 is lossy, so a little detail is removed. From a WAV or FLAC source at 192 kbps or more, most people cannot hear a difference.
