Which compression setting should I choose?Use "Balanced" for most purposes (good quality with significant size reduction). Choose "Small File" for maximum compression or "High Quality" for minimal quality loss.
How much can I compress an audio file?Compression depends on the original format and target settings. Typically, you can achieve 50-80% size reduction while maintaining good audio quality.
Audio file not uploading? Make sure you're uploading a supported audio format. Check that the file isn't corrupted.
Compression fails immediately? Try a different audio file or refresh the page. Some rare audio codecs may not be supported.
Compressed audio sounds distorted? Try using a higher bitrate setting or the "High Quality" preset for better audio fidelity.
File size didn't reduce much? If your original file is already highly compressed (like low-bitrate MP3), further compression may be minimal.
