Audio Sample Browser and Waveform Viewer

Audio Sample Browser and Waveform Viewer is a fast audio sample pack explorer, stereo
waveform inspector, tempo estimator, and musical pitch analyzer built for music producers,
beatmakers, and sound designers on Linux.
An independent Linux alternative inspired by rapid desktop sample audition browsers, it
decodes uncompressed and compressed audio files to display detailed stereo envelopes,
transient markers, harmonic spectra, BPM estimates, and fundamental musical key readouts.

Key Features:
- Multi-Format Sample Pack Explorer: Browses local folders of .wav, .flac, .aiff, .ogg,
.opus, .mp3, and .m4a samples with favorites bookmarking, category filtering, and
instant metadata inspection.
- Stereo Waveform & Transient Markers: Renders high-contrast Left/Right peak and RMS
waveforms overlaid with detected percussive transient onset markers and dBFS rulers.
- Real BPM & FFT Pitch Key Detection: Estimates loop tempo via onset energy envelope
autocorrelation and identifies fundamental musical pitch, note name (e.g. A4 440.0 Hz),
and cents offset via windowed FFT harmonic spectrum analysis.
- Audition Playback & Normalized WAV Export: Provides transport playback controls plus
one-click silence-trimmed and peak-normalized 16-bit PCM .wav sample export.
