WAV to Text

WAV is the professional's format: what your Zoom or Tascam field recorder writes, what the DAW exports, what the studio hands you after a session. It's uncompressed and huge — a two-hour interview can run past a gigabyte — and most lightweight transcription tools choke on exactly the files where the content matters most.

Castmagic is built for long-form audio. Upload the WAV (or paste a link from cloud storage), and get back a full transcript with speaker labels, timestamps, and paragraph structure. The lossless source quality works in your favor: cleaner input, cleaner transcript.

Who transcribes WAV files

Journalists and documentary producers with field-recorder interviews. Podcast producers working from raw session audio before the edit. Researchers with focus-group recordings. Musicians and engineers who need the spoken parts of a session — interviews, voiceovers, songwriting conversations — on paper.

In every case the WAV is the source of truth, and transcribing it directly (rather than a compressed copy) means the transcript and the master share the same timeline — timestamps in the text line up with the audio you'll actually edit.

No conversion before the conversion

There's no need to compress the WAV to MP3 first just to make a transcription tool happy. Upload the original — the uploader handles large files, and the transcription works from the full-quality audio.

Timestamps that match your edit

Castmagic tracks word-level timing, so exports can carry timestamps at whatever granularity the job needs: paragraph marks in the text export for skimming, exact cue timing in SRT/VTT if the audio becomes a video, and per-utterance start/end times in CSV for logging and analysis.

After the transcript

Pull quotes for the article, generate a summary for the producer, draft show notes for the episode the session becomes — Castmagic's AI presets work from the transcript, so the WAV's content flows into every written deliverable without retyping.
