🔗 Open Merge AudioFrequently Asked Questions
Can I merge different audio formats together?
Yes. AudioTools.space decodes files in the browser, so you can combine MP3, WAV, OGG, FLAC, AAC, and M4A files before exporting the merged result as WAV, MP3, or OGG.
Should I use gaps or crossfades?
Use small gaps for speech, podcasts, audiobooks, and lessons where a natural pause between segments is appropriate. Use crossfades for music, ambient audio, or tracks that should flow smoothly without a break.
Does AudioTools.space have a file upload limit?
There is no server-side limit because files are processed locally in your browser. The practical limit is your device's available memory, which comfortably handles typical podcast and audio project sizes.
Can I trim individual tracks before merging?
For per-track trimming before merging, use the Audio Trimmer to prepare each clip first, then bring the trimmed files into the Merge Audio tool.
