Frequently Asked Questions - WAV to MP3
How much does the size reduce when converting WAV to MP3?
Example: a 30 MB WAV (3 min song) converts to ~3 MB MP3. Typical 90% reduction. An album of 10 songs goes from 300 MB to 30 MB.
Is the quality loss noticeable?
For the average human ear, no. Our quality options (128-320 kbps) remove only inaudible frequencies. Audiophiles may notice subtle differences at lower bitrates, but for podcasts, casual music, and voice it's imperceptible.
When should I NOT convert WAV to MP3?
Don't convert if: 1) You need to edit audio professionally (better keep WAV), 2) You're a music producer and need maximum fidelity, 3) You'll convert the audio multiple times (each conversion loses quality).
Can I reconvert MP3 to WAV to recover quality?
No. Converting MP3 → WAV only increases file size, it doesn't recover lost quality. The resulting WAV still has the quality of the original MP3.
What bitrate should I choose for studio recordings?
We offer several options depending on your needs (128kbps, 192kbs and 320kbps), ideal for casual listening and sharing. If you're archiving professional recordings, consider keeping the original WAV and only converting copies for distribution. For critical listening or mastering work, WAV is always better than MP3.
Why are my recordings so large in WAV format?
WAV is uncompressed, storing every audio sample without reduction. A 3-minute song at CD quality (44.1kHz, 16-bit stereo) is ~30 MB. MP3 compresses this to ~3 MB by removing inaudible frequencies your ears can't detect anyway.
