关于3GP转WAV
3GP stores audio as AMR (narrow-band at 8 kHz, 4.75-12.2 kbps) or AAC within the 3GPP mobile container. WAV (Waveform Audio File Format), co-developed by Microsoft and IBM in 1991, stores uncompressed PCM audio data — the raw digital representation of sound. Converting 3GP to WAV extracts the audio stream, decodes it completely, and stores the raw samples in the most universally compatible uncompressed audio format available.
为什么要将3GP转换为WAV？
WAV is the universal input format for audio editing, mastering, analysis, and processing. Every audio editor (Audacity, Adobe Audition, Pro Tools, FL Studio, Reaper), speech recognition system, forensic audio tool, and scientific analysis software accepts WAV without question. Unlike FLAC or ALAC, WAV requires zero codec support — it is raw PCM data with a simple header, making it the safest choice when you do not know what software will process the audio next.
常见使用场景
- Importing 3GP voice recordings into Audacity or Adobe Audition for editing and cleanup
- Feeding 3GP audio to speech recognition or transcription software that requires WAV input
