10-Band Audio Equalizer Studio

10-Band Audio Equalizer Studio is a desktop audio equalization and mastering
workbench for Linux featuring interactive 10-band ISO graphic faders, parametric
Q-factor shaping, real-time digital biquad transfer curve plotting, A/B listening
preview, and lossless multi-format audio rendering. A lightweight Linux
alternative to EqualizerPro for music mastering, podcast voice shaping, and
library batch equalization.

Key Features:
- Interactive 10-band ISO equalizer (31 Hz, 62 Hz, 125 Hz, 250 Hz, 500 Hz, 1 kHz,
2 kHz, 4 kHz, 8 kHz, 16 kHz) with -18 dB to +18 dB gain faders, per-band Q
factor (0.3 to 8.0), and customizable center frequencies.
- Master Preamp (-15 dB to +15 dB), Sub-Bass low-shelf boost (20-120 Hz), and
brickwall lookahead limiter (alimiter) to prevent digital clipping.
- Live composite dB Biquad transfer curve (20 Hz to 20 kHz logarithmic Bode plot)
with draggable band nodes and overlaid real FFT audio spectrum.
- 12 built-in mastering presets (Flat, Bass Boost, Sub-Bass Punch, Vocal Presence,
Podcast, Classical, Rock, Electronic, Acoustic, Jazz Warmth, Treble Air, Late
Night Loudness) plus JSON preset import/export.
- Instant A/B playback preview (Bypass Original vs. EQ Active) via PulseAudio,
PipeWire, or ALSA, and high-speed batch rendering to FLAC, WAV (16/24-bit PCM),
MP3 (libmp3lame), and OGG Vorbis via the bundled FFmpeg filtergraph.
