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.

Very high accuracy transcription with noisy tapes / accents. The ability to edit as you listen is incredible. I haven't been impressed with code to this extent sin...

Sonix is easy to use. Ridiculously easy. And even though the accuracy wasn't perfect it saved several days in a typical transcription cycle and the hourly cost we usually pay.
