Waveform Audio Trim and Fade Studio

Waveform Audio Trim and Fade Studio is an interactive desktop stereo PCM audio
waveform editor, loudness normalizer, and batch audio processor for Linux.
A lightweight Linux alternative to Waveosaur for sample-accurate audio trimming,
envelope shaping, loudness normalization, and multi-format batch export.

Key Features:
- Interactive Stereo Waveform Canvas: Renders dual-channel Left and Right peak
and RMS envelopes with dBFS and millisecond rulers, zoom controls, zero-crossing
snap, and visual Start/End sample selection handles.
- Sample-Accurate PCM & FFmpeg DSP Operations: Trim/Crop to selection, Cut/Delete
range, Auto-Trim leading and trailing silence by dBFS threshold, Smooth Fade-In
and Fade-Out curves, Reverse, DC-Offset bias removal, Peak dBFS normalization,
EBU R128 integrated loudness normalization (loudnorm), and Speed/Pitch shifting.
- Multi-Level Undo & Redo History: Preserves session PCM snapshots so edits can
be stepped backward and forward non-destructively before final export.
- Batch Audio Processor & Multi-Format Export: Processes queues of audio files
through automated silence trim, DC-offset removal, fade, and loudness chains,
exporting to WAV, FLAC, MP3, and Ogg Vorbis alongside Loudness & Spectrum reports.
