Understanding WAV files

What is a WAV file?

Uncompressed audio standard for professional recording

WAV files are audio files saved in the ‘Waveform Audio File Format,’ a highly standardized digital audio format created by Microsoft and IBM. It is the most popular way of storing audio waveform data on computers. WAV files can be saved with different sampling and bitrates. WAV files usually contain raw, uncompressed audio data and their file sizes can be quite large. It is normally saved for CD quality audio with 44.1 KHz, 16-bit, stereo format. WAV files are similar to .AIF files, but they are based on the Resource Interchange File Format (RIFF), rather than the Audio Interchange File Format (AIFF). Hence, WAV files are more popular on the Windows platform while AIF files are more popular on MacOS systems.

Common uses for WAV files

  • Professional audio recording
  • Music production
  • Sound design
  • Broadcast audio
  • Audio mastering
  • Professional recording studios
  • Audio interfaces
  • Windows Sound Recorder
  • DAW exports
  • Broadcast equipment

Who works with WAV files?

Court reporters, legal teams, and oral-history archivists record depositions and interviews in WAV when bit-perfect audio matters more than file size, and academic researchers often standardize on it for qualitative interview data. Game developers and film post-production teams also work in WAV for dialogue stems and source audio before final delivery.

WAV vs FLAC: which should you use?

WAV stores raw, uncompressed PCM audio, while FLAC applies lossless compression that typically shrinks the same recording to roughly half the size with no loss in quality. WAV has near-universal support in recording hardware, DAWs, and editing software, whereas FLAC is preferred for archiving and file transfer because of its smaller footprint. Choose WAV for recording and editing where compatibility matters; choose FLAC when storage space or upload time is the priority.

WAV conversion FAQ

WAV subtitles: frequently asked questions

What subtitle formats can I export from WAV?

Sonix exports WAV transcriptions to supported subtitle formats: SRT, VTT, and TTML. Choose the format your video software or streaming platform requires.

Does WAV quality affect subtitle accuracy?

Yes! WAV's uncompressed audio provides the best possible source for transcription, resulting in more accurate subtitles compared to heavily compressed formats. The difference is most noticeable for challenging audio.

Can I create subtitles for studio recordings?

Absolutely! Sonix handles professional studio WAV files perfectly. High-quality source audio means highly accurate subtitles for your video projects.

What's the best subtitle format for WAV-to-video?

SRT is the most widely compatible format for video editing and streaming. For web video, VTT is preferred. Sonix supports both plus many professional formats.

How do I improve subtitle timing from WAV?

WAV's clean audio already provides excellent timing. Use Sonix's visual editor to make any fine adjustments - waveform display helps you align subtitles perfectly.

Can I create hardcoded subtitles from WAV?

Sonix generates subtitle files in supported formats like SRT, VTT, and TTML. Import these into your video editor to burn subtitles directly into your video (hardcoding).

Do I need to convert WAV to MP3 before transcribing?

No, WAV files can be uploaded and transcribed directly. Keeping the original WAV avoids the compression artifacts an MP3 conversion introduces, though the larger file may take longer to upload.

Why are my WAV files so large?

WAV stores uncompressed PCM audio, so CD-quality stereo uses roughly 10 MB per minute. Converting to a compressed format like FLAC or MP3 reduces the size if you need to save space after transcription.
