Frequently Asked Questions
Will compression reduce audio quality?
Some quality loss is inevitable with compression. Higher quality settings minimize loss but create larger files. Find your quality/size balance.
What compression format should I use?
MP3 is widely compatible and offers good compression. AAC provides better quality at similar file sizes. Experiment based on your needs.
What quality setting should I use?
For music: 192-320 kbps. For podcasts/speech: 128 kbps acceptable. Lower bitrates create smaller files but reduced quality.
Can I compress multiple files at once?
Batch processing allows compressing multiple audio files simultaneously, saving time for large projects.
