How to change audio quality:

Select a single audio file (MP3, WAV, OGG, M4A, FLAC, etc.)
Drag the Quality Dial to your desired level, or fine-tune the sample rate
Pick MP3 (smaller, bitrate-based) or WAV (uncompressed, sample-rate-based)
Click "Change Quality" – re-encoding happens locally in your browser
Preview the result and download the file at its new quality

About Quality

The Quality Dial links MP3 bitrate and sample rate into one control — drag right for clearer audio and a bigger file, left for smaller and rougher.

Choosing WAV removes bitrate from the equation entirely: since WAV is uncompressed, quality there is set purely by sample rate (and a fixed 16-bit depth).

You can still override the sample rate manually below the dial if you want a specific value regardless of the quality level.
