Large WAV files
WAV is uncompressed, so every consonant the microphone caught is still there. That usually means fewer mistakes than a low-bitrate MP3 of the same recording.
The trade-off is size. A long WAV can be hundreds of megabytes. Since nothing uploads here, size only affects how long your browser takes to read the file.
A WAV can be huge and it still stays on your computer. The browser reads it locally. The speech model downloads once from the Hugging Face hub and is cached for the next recording.

WAV to Text FAQ
Is my WAV uploaded anywhere?
No. The WAV is read and transcribed in your browser. A large studio file is not sent to Script Timer. The speech model downloads once from the Hugging Face model hub and your browser caches it.
Is WAV transcription free?
Yes. A WAV transcript needs no sign-up and adds no watermark. One file can run up to 60 minutes.
What model reads a WAV?
OpenAI's open-source Whisper model, run in the browser with transformers.js. Fast uses Whisper Tiny. Accurate uses Whisper Base, which is the better default for an interview with room noise.
Why is the first WAV slower?
The first WAV waits while the browser downloads the speech model. Later recordings use the cached model. A long WAV can also take a moment to open because the file itself is large.
Why transcribe the WAV instead of an MP3?
WAV is uncompressed, so consonants that a low-bitrate MP3 would blur are still in the file. That usually means fewer mistakes on the same take.
How big a WAV can I transcribe?
Up to 60 minutes. A long WAV can be hundreds of megabytes, so use a computer rather than a phone. Nothing uploads, so the size only affects how long your browser takes to read the file.
