Frequently Asked Questions

WAV is uncompressed and ideal for audio editing in DAWs (Digital Audio Workstations) like Audacity, Pro Tools, and Logic Pro. While AAC is great for listening, WAV provides the clean, uncompressed format needed for professional editing and processing.

No. AAC is lossy, so the original lost data cannot be recovered. Converting to WAV creates an uncompressed file but doesn't restore lost audio information. However, WAV prevents further quality loss during editing.

Choose 'Original' to maintain the source sample rate. Use 48kHz for video production, 44.1kHz for music CDs, or 96kHz for high-resolution audio work. Higher rates create larger files without audible benefit from AAC sources.

WAV files are 8-10x larger than AAC. A 5MB AAC file becomes 40-50MB as WAV. This is because WAV is uncompressed. Ensure you have adequate storage space before converting large libraries.

Yes! M4A files typically contain AAC audio. This converter handles both .aac and .m4a file extensions. The conversion process is identical for both formats.

Currently, this tool processes one file at a time for optimal browser performance. For batch conversion, process files sequentially. Each conversion maintains your selected sample rate settings.

WAV has limited metadata support compared to AAC. Basic information may be preserved, but AAC's rich ID3 tags might not fully transfer. You may need to re-add metadata in your audio editing software.

Yes, if you're doing serious editing. Working with uncompressed WAV prevents compounding quality loss from multiple edits. Edit in WAV, then export to your desired compressed format (AAC, MP3) when finished.

Both are uncompressed audio formats. WAV is the Windows standard, AIFF is the Mac standard. They're functionally equivalent. WAV is more universally compatible across platforms and software.

No. All processing happens entirely in your browser using FFmpeg WebAssembly. Your audio files never leave your device, ensuring complete privacy.
