Frequently asked questions
Does converting MP3 to WAV improve quality?
No. The WAV holds exactly what the MP3 decoded to; detail removed by MP3 compression does not come back. WAV only avoids adding further loss while you edit.
Why is there no bitrate choice?
WAV is uncompressed PCM, so bitrate follows from sample rate, bit depth and channels. The bitrate menu is disabled for WAV on purpose.
Which sample rate should I choose?
44.1 kHz matches CD audio and most MP3s. Use 48 kHz for video projects.
Is there a size limit?
The first conversion downloads about 32 MB of processing code. Files are processed one at a time on your device and kept in memory, so very long recordings need a device with plenty of RAM.
Is it private?
Yes. Nothing is uploaded.
