FAQ do formato de arquivo WAV
WAV (.wav) files store uncompressed PCM audio data, preserving full fidelity at the cost of larger file sizes. Common in professional audio recording and editing, they support various sample rates and bit depths. Use sample .wav files to verify read/write performance, channel configurations, and metadata chunk parsing in audio pipelines.

WAV File Format FAQ
Para que WAV e mais usado?
WAV aparece em 1 workflows de categoria nesta biblioteca e e usado com frequencia em pipelines de audio.
Como devo testar o suporte a WAV em CI?
Comece pelos hubs especificos por categoria acima, consulte os manifests de fixtures e valide o comportamento do parser em varios tamanhos de arquivo e sinais MIME.

What sample rates do the WAV fixtures cover?
The library includes 8kHz (telephony), 22kHz, 44.1kHz (CD), 48kHz (broadcast), and 96kHz reference samples. Use lower rates for voice pipeline tests and 44.1/48kHz for production audio workflows.
What is the difference between PCM and other WAV encodings?
Standard WAV uses uncompressed PCM (16-bit or 24-bit). WAV can also hold ADPCM, IEEE float, or extensible format audio. PCM is the universal baseline; exotic encodings require codec-aware parsers.
Why are WAV files so much larger than MP3 at the same duration?
WAV/PCM stores raw samples without compression. A 60-second stereo 44.1kHz 16-bit WAV is ~10MB; the same audio as 128kbps MP3 is ~940KB. Use WAV fixtures when testing uncompressed ingest or lossless reference quality.
