Upload audio files

This page covers how to get audio into a VoiceQC Session. For the broader “first run” flow, see the Quickstart.

What VoiceQC accepts

• Format: WAV only. Files with the MIME type audio/wav are accepted; everything else is silently ignored.
• Multiple files at once. Drop several files together or pick many files in the dialog — they all upload in parallel. (Dropping a folder isn’t supported; select the files inside it.)
• No length cap surfaced in the UI today. Very long files take proportionally longer to transcribe; if a file fails to process, the Session item shows an error state and you can retry.

Non-WAV files disappear without an error

If you drag-drop an MP3, M4A, FLAC, or anything other than WAV, the browser filter quietly drops it. You won’t see a rejection message — the file simply doesn’t appear in the Session items table. Re-export from your DAW as 16-bit PCM WAV if a file you expected isn’t showing up.

Upload via drag-drop

1. Open the Session page (the Session link in the top nav, or click into an existing Session from Logs).

2. Find the Drag and drop files here zone in the page body.

3. Drag one or more .wav files from your file manager onto the zone and release.

Each WAV starts uploading immediately and appears as a row in the Session items table below the drop zone.

Upload via file picker

1. On the Session page, click Choose Files under the drop zone.

2. The OS file picker opens with the filter already set to WAV. Select one or more files and click Open.

The picker won’t display non-WAV files, so this path is the safer of the two if you have a folder mixed with other audio formats.

What happens after you drop

Each WAV starts uploading immediately and appears as a row in the Session items table once the upload completes. Transcription runs in the background — typically seconds to a minute per file depending on length. The row fills in with the transcribed text the moment it’s ready. You don’t need to refresh.

For the picture of what’s happening between drop and result, see How transcription works.

Why didn’t my upload work?

Three things almost always explain a missing or stuck file. Check them in this order.

A file I dropped didn’t show up

Almost always a format issue — re-export as WAV (16-bit PCM is the most reliable). If the filename has unusual characters (<, >, :, ", /, \, |, ?, *), the upload may sanitize the name on the way in; you’ll see the sanitized version in the table.

The row is stuck on “uploading” or never transcribes

Refresh the page. The Session items table re-syncs and an item that did finish will populate its transcription on reload. If a refresh doesn’t help, VoiceQC may be processing a lot of audio just now — wait a minute and reload.

I’m at my Plan limit

Items past your character/item limit for the current Usage period are rejected before they upload. Check Plan limits and the Usage dashboard to see where you stand.
