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 Questions

Everything about WAV to text

Can Sonix transcribe WAV files?

Absolutely! WAV files provide the best possible audio quality for transcription since they're uncompressed. Sonix processes WAV files from any source - professional studio recordings, broadcast audio, voice recorders, or DAW exports. The pristine audio quality translates directly to transcription accuracy.

Is WAV better than MP3 for transcription?

WAV's uncompressed audio can provide marginally better transcription accuracy compared to compressed formats, especially for challenging audio with background noise or multiple speakers. However, for most clear speech recordings, the difference is minimal. WAV files are significantly larger, so MP3 may be more practical for long recordings.

How long does it take to transcribe a WAV file?

Despite larger file sizes, Sonix transcribes WAV files at approximately 10x faster than real-time. Upload times may be longer due to file size, but processing is equally fast. A 30-minute WAV recording (approximately 300MB at CD quality) transcribes in about 3 minutes after upload.

What WAV specifications work best for transcription?

Standard CD-quality WAV files (44.1kHz sample rate, 16-bit depth, stereo) work excellently for transcription. Higher resolutions like 48kHz/24-bit also work well but don't improve transcription accuracy. Mono files are fine for speech-only content and upload faster.

Can I transcribe WAV files with multiple audio channels?

Yes! Sonix handles stereo WAV files and can transcribe multi-channel recordings. For interviews recorded with separate microphones per speaker, our speaker diarization accurately identifies who is speaking on each channel, making it easy to follow the conversation.

Should I convert WAV to MP3 before transcribing?

No conversion needed! Sonix accepts WAV files directly. While converting to MP3 reduces upload time and storage, it also slightly reduces audio quality. If you have the bandwidth for larger uploads, transcribing WAV directly preserves maximum quality for the most accurate results.
