Frequently Asked Questions
Can I merge files in different formats (e.g. MP3 and WAV)?
Yes. Each file is decoded to PCM audio before being joined, so different input formats and bitrates are handled automatically. The output is always MP3 at 192 kbps, which is compatible everywhere.
Is there a gap or click between the merged files?
No. The files are concatenated at the sample level by FFmpeg's concat filter. There is no silence, gap, click, or crossfade added between tracks — they join seamlessly at their natural boundaries.
How many files can I merge at once?
You can merge 2 to 5 audio files per job. If you need to merge more, merge the first 5, then merge the result with additional files in a second job.
What is the output quality?
The merged file is exported as MP3 at 192 kbps, which delivers near-CD quality and is widely supported. If you need a lossless format, consider using a desktop tool like Audacity.
Is this audio merger completely free?
Yes — no account, no watermarks, no subscription required. Add your files, set the order, and download the merged result.
How long are my files kept on the server?
Both the uploaded files and the merged output are automatically deleted after 60 minutes. We never store, sell, or analyse your audio content.
