Frequently Asked Questions

Why compress WAV files to MP3? +
WAV files are incredibly large and difficult to email, share online, or store in large quantities on mobile devices. Converting them to MP3 shrinks the file size by up to 90%, making them highly portable and streamable.
How much quality is lost during the MP3 conversion? +
MP3 is a lossy format, so some high-frequency data is removed. However, if you choose a high bitrate like 320 kbps, the resulting audio will be virtually indistinguishable from the original WAV for the average listener.
Does the converter preserve stereo audio? +
Yes. The tool faithfully preserves the stereo field, sample rate, and audio panning of your original WAV master file during the MP3 compression process.
