O převodu 3GPP na WAV

WAV (Waveform Audio File Format) is the most widely supported uncompressed audio format, storing raw PCM samples that every audio tool, operating system, and programming library can read without any codec dependencies. Converting 3GPP video to WAV extracts the audio into the most universally accepted working format for audio editing, analysis, transcription, and processing.

Proč převádět 3GPP na WAV?

WAV is the expected input for the majority of professional audio workflows. Speech-to-text APIs (Google Speech, Amazon Transcribe, Whisper), audio analysis tools (Praat, Audacity spectral views), forensic audio software, and most programming libraries (Python's wave module, JavaScript's Web Audio API) all work best with WAV input.

As an uncompressed format, WAV ensures no additional artifacts are introduced during extraction. Every sample from the decoded 3GPP audio is preserved exactly as decoded, providing the most faithful representation of the original recording for any downstream processing.

Běžné případy použití

Feeding extracted audio into speech recognition or transcription services
Importing phone recordings into any DAW for editing and mixing
Providing audio input for spectral analysis or forensic audio examination
Creating a universal working copy before encoding to any final delivery format
Processing phone audio through Python scripts or command-line audio tools

Jak to funguje

FFmpeg decodes the audio from the 3GPP container (AMR or AAC) and writes uncompressed PCM data in a WAV container. Output sample rate matches the source (8 kHz for AMR, up to 48 kHz for AAC) unless overridden. Standard output is 16-bit signed integer PCM. WAV supports sample rates up to 655 kHz and bit depths up to 32-bit float.

Kvalita a výkon

WAV is uncompressed — it stores the exact decoded PCM data without any further processing or loss. The output quality equals the decoded 3GPP source quality, no more and no less. For AMR-sourced audio at 8 kHz, the WAV faithfully reproduces the narrowband telephony-grade sound.

Tipy pro nejlepší výsledky

1Match output sample rate to the source — upsampling wastes space without improving content quality.
2Use 16-bit depth for AMR-sourced audio. 24-bit and 32-bit float are unnecessary for narrowband telephone-quality content.
3WAV is the safest input format for any audio processing pipeline — when in doubt, start with WAV.
4For archiving large collections, convert to FLAC instead of WAV to save approximately 50% storage.
5If your processing tool requires a specific sample rate (like 16 kHz for some speech models), set it during the WAV conversion rather than doing a separate resampling step.

3GPP to WAV is the go-to conversion for audio editing, analysis, and processing workflows. WAV's universal compatibility and uncompressed nature make it the safest intermediate format for any audio task.

Často kladené otázky

Much larger. AMR at 12.2 kbps produces ~90 KB/minute. The same content as 16-bit WAV at 8 kHz is ~960 KB/minute — about 10x larger.

Only if a specific tool requires it. Upsampling 8 kHz AMR audio to 44.1 kHz does not add real audio content and increases file size ~5x.

Yes. WAV is the preferred input format for Google Speech-to-Text, Amazon Transcribe, Azure Speech, Whisper, and most other speech recognition services.

Both are lossless. WAV is simpler and more universally supported. FLAC is ~50% smaller with rich metadata. For working copies, use WAV. For long-term storage, FLAC saves space.

Yes, though AMR source audio is always mono. You can request stereo output, but it will be dual-mono (same signal in both channels).
