This text is added after every original file name, exactly as typed.
Output
Each file is downloaded as soon as it is ready. Your browser may ask once to allow multiple downloads.

How the batch queue works
01. Add your files
Drop as many WAV, AIFF or compressed files as you need into the queue.
02. Set the target once
One sample rate, bit depth and format for the whole queue.
03. Convert all
Files are converted one at a time and saved as each one finishes.
Your audio stays on your device
Every file is read, converted and written in your browser, one at a time. Nothing is uploaded. Only the file being converted is held in memory; each finished file is saved and released before the next one starts.
Frequently asked questions
- Is the quality the same as the single-file Sample Rate Converter?
- Yes. Each file goes through exactly the same converter: the same filtered resampling, the same metadata handling and the same file writer. Batch only adds the queue around it.
- Can I mix sample rates in one batch?
- Yes. Pick one target rate, for example 48 kHz, and every file is converted to it whatever its source rate. A file already at the target rate is written without resampling.
- What happens to timecode and metadata?
- For WAV output, broadcast timecode is recalculated for the new rate, iXML is updated, markers are moved to the right positions, track names are kept and a line is added to the recorder history, exactly like the single-file tool.
- Are files saved one by one?
- Yes. In Chrome and Edge you can choose an output folder once and every file is written there as soon as it is ready. In other browsers each file is downloaded as it finishes. There is no ZIP to wait for.
- What if one file is damaged?
- That file is marked as failed with the reason, and the queue carries on with the next one. Retry failed runs only the files that failed.
- Who can use batch processing?
- Batch Processing is a Lifetime Pro feature. It does not use your free conversion or pay-per-use credits.
