AI Transcription Audio File Size Cost Estimator
Estimate AI transcription costs based on audio/video file size and format. Compare Whisper, Google Cloud, and AWS Transcribe costs instantly.
Audio Duration and Cost Formulas
We convert the binary file size into playing minutes based on the audio bitrate, and then apply per-minute API provider pricing.
Bitrates are preset based on standard formats: MP3 (128-320 kbps), WAV (768-1411 kbps), AAC (192-256 kbps).
