Convert multiple audio files
Import multiple audio files, apply one output format to the whole batch, then download every result.
What does this template do?
Import multiple audio files, apply one output format to the whole batch, then download every result.
This template applies one output format to a whole series of audio files: import the collection, pick MP3, WAV, FLAC, OGG, M4A or Opus once, and get each converted file back under its own name. It helps when a player, platform or editing program only accepts one format.
Pipeline steps
This template automatically chains 3 steps in the Workspace. You can review every setting before running it.
- 1Import several audio files
- 2Convert the audio
- 3Download the audio files
Why the steps come in this order
Conversion sits between importing the collection and the grouped download: every file goes through the same encoder with the same settings, so the batch stays consistent. There is no merge step; the files remain separate from start to finish.
When should you use this template?
- Convert voice recorder files to MP3 so they are easy to share.
- Turn a series of editing WAV files into FLAC for lossless archiving.
- Prepare OGG or M4A files for a player that only reads MP3.
Local processing in your browser
When the selected modules support local processing, your files stay on your device while the Pipeline runs.
Settings to check
- Output format: MP3 by default. MP3 and M4A (AAC) are encoded at 192 kbit/s, OGG Vorbis at quality 5, Opus at 128 kbit/s.
- FLAC and WAV keep the decoded signal without further loss; the WAV output is 16-bit PCM.
- Collection order: it does not change the result, each file is converted on its own.
Example
- Before
- 12 voice memos in M4A, each 2 to 10 minutes long.
- After
- 12 MP3 files at 192 kbit/s, downloaded together, one per memo.
Limits to know
- Converting one compressed format into another (M4A to MP3, for instance) adds a second loss: keep the originals.
- Cover art, chapters and format-specific tags are not guaranteed in the converted file.
- Everything runs in the browser: a batch of long files needs memory and time on a modest device.
