Instant Audio Transcription: Fast Results from Any Recording
Upload your recording and get a complete transcript — with speaker labels — in minutes. BrassTranscripts processes a 1-hour file in roughly 6–15 minutes. No subscription, no commitment.
BrassTranscripts completes audio transcription at roughly 10–25% of the recording's duration, so a 60-minute interview typically produces a finished transcript in 6–15 minutes — a turnaround that manual transcription services measure in hours or days. Automatic speaker identification is included in every job, with no extra step or add-on fee required.
How Instant Transcription Works
BrassTranscripts uses a cloud-based AI transcription engine that runs on dedicated GPU infrastructure — not shared queues. That's what keeps processing times short even for long recordings.
Upload Your File
Drop any audio or video file onto the upload form. Accepts MP3, M4A, WAV, AAC, FLAC, OGG, Opus, WebM, MPGA, MP4, and MPEG — up to 450 MB per file.
AI Processing Begins Immediately
The AI transcription engine starts the moment your upload completes. There is no queue — your job runs on its own dedicated compute. Processing takes approximately 10–25% of your recording's duration.
Speaker Labels Applied Automatically
Automatic speaker identification runs alongside transcription. When processing completes, each speaker's turns are labeled throughout the transcript — no manual review step required.
Preview Before You Pay
Once processing finishes, the first 30 words of your transcript are shown at no charge. Verify the transcription quality and speaker separation before purchasing the full result.
Download All 4 Formats
Every purchase includes TXT, SRT, VTT, and JSON — all in one flat price. No add-on charges for individual formats.
Transcription Speed by Recording Length
BrassTranscripts processes audio at roughly 10–25% of the recording's duration. The range reflects file complexity — more speakers, background noise, and varied audio quality all affect processing time. These are typical observed ranges, not guarantees.
| Recording Length | Typical Processing Time | Price |
|---|---|---|
| 5 minutes | 30–75 seconds | $2.50 |
| 15 minutes | 90 sec – 4 min | $2.50 |
| 30 minutes | 3–8 minutes | $6.00 |
| 60 minutes | 6–15 minutes | $6.00 |
| 90 minutes | 9–23 minutes | $6.00 |
| 2 hours | 12–30 minutes | $6.00 |
Processing times are based on observed production jobs. Audio with overlapping speakers or heavy background noise may take longer. Price is the same regardless of duration for 16+ minute files.

Tips for the Fastest Possible Turnaround
Processing time is largely fixed by recording length and complexity — but a few upload choices affect how fast and cleanly the job completes.
Use compressed audio when possible
MP3 and M4A upload faster than uncompressed WAV files. A 1-hour WAV can be 10× the size of the equivalent MP3 — smaller files reach the processing queue sooner.
Clear audio processes faster
Heavy background noise, overlapping speakers, or very low volume increases the processing window. Clean recordings with one or two clearly separated speakers land at the lower end of the time range.
Don't trim the file — just upload
You don't need to edit or pre-process the file before uploading. The AI transcription engine handles silence, pauses, and filler words automatically.
