Batch Video Audio Track Extractor

Batch Video Audio Track Extractor is a desktop audio demuxing and transcoding
workbench for extracting soundtracks and multi-language audio streams from
MP4, MKV, WebM, MOV, AVI, and TS video containers.
A lightweight Linux alternative to Pazera Free Audio Extractor for instant
lossless audio stream copy, format conversion, time slicing, and loudness
normalization.

Key Features:
- Multi-Stream Audio Inspector: Probes video containers via bundled FFmpeg to
display every embedded audio track with codec, bitrate, sample rate, channel
layout, and language metadata.
- Instant Lossless Stream Copy: Demuxes elementary audio tracks directly without
re-encoding (-vn -acodec copy) into native .m4a, .opus, .ogg, .ac3, .mp3,
.flac, or .wav files with zero quality loss.
- Batch Audio Transcoding & Slicing: Converts selected or all multi-language
tracks to FLAC, WAV, MP3, Opus, AAC, or Ogg Vorbis with custom bitrate,
sample rate, channel downmix, and start/end timestamp slicing.
- EBU R128 Loudness & Waveform Verification: Supports integrated loudness
normalization (loudnorm / dynaudnorm / dB gain) and renders real decoded PCM
waveform envelopes alongside measured Peak and RMS dBFS levels.
