Prepare a WAV recording for transcription
WAV recordings often come from recorders, audio editors, and recording sessions. You can upload the WAV itself to create a text draft, then use the original audio to check passages that need closer listening.
Use the recording you actually need
For a finished interview or podcast, choose the final spoken edit rather than a session containing repeated takes and long setup sections. If your editor holds separate microphone tracks, export the conversation you want transcribed as an audio file. An editing project file is different from a playable WAV recording.
Consider clarity as well as file size
WAV files can be larger than compressed copies of the same recording. Check the upload allowance shown for your plan before choosing a long file. There is no need to create a WAV from an existing MP3 just for transcription: changing the container or encoding cannot restore missing detail.
Listen for clipping, room echo, and a quiet second speaker. A large file alone does not guarantee clear speech. When you have multiple source recordings, a close microphone recording may be more useful than a noisier room recording.
Keep a review copy and a reading copy
Review the transcript against the audio before quoting it. Export DOCX when you want to add headings and editorial notes, or TXT when you need a simple text file. If the recording will accompany a video, an SRT export provides timed cues; check those cues against the finished video before publication.
Frequently Asked Questions
Is WAV better than MP3 for transcription?
WAV is uncompressed, so it preserves full audio quality. This can produce slightly more accurate transcripts, especially for challenging audio.
WAV files are large — is there a size limit?
Free users can upload up to 1.3 GB. Pro users get 15 GB per file, which covers even very long WAV recordings.
How fast is WAV to text conversion?
Most WAV files are transcribed in under a minute, even for long recordings.
