Frequently Asked Questions
How do I merge multiple audio files?
Upload two or more audio files, arrange them in your desired order using the up/down arrows, then click Merge Audio Files. The tool combines them into a single WAV file.
Can I merge files in different formats?
Yes. You can mix MP3, WAV, OGG, FLAC, and other formats. The tool automatically decodes all files and resamples them to a consistent sample rate before merging.
Can I reorder the files?
Yes. Use the up and down arrow buttons next to each file to change the order. Files are merged in the order shown in the list.
Is there a limit on how many files I can merge?
There's no hard limit on the number of files. However, very large combined audio may take longer to process depending on your device's memory and processing power.
Are my files uploaded to a server?
No. All merging happens locally in your browser using the Web Audio API. Your files never leave your device.
What if my files have different sample rates?
The tool automatically resamples all files to match the highest sample rate among your uploaded files, ensuring the best possible quality.
