> 100% client-side, zero-server-load audiophile studio built on the Web Audio API, IndexedDB, and Offline PWA technologies.

Created by **Kamal Swami** ([https://kamalswami.in](https://kamalswami.in))

## Core Capabilities
- **32-bit Web Audio DSP Chain:** Preamp (±12 dB), Subsonic Filter (18 Hz), Tube Saturation (4x oversampled WaveShaper), Tone (80 Hz / 8 kHz), 10-Band Graphic EQ, 5-Band Parametric EQ, Stereo Width (Haas delay), Convolution Reverb (Room, Hall, Plate, and custom `.wav` Impulse Responses), Dynamics Compressor, Brick-Wall Peak Limiter (-1 dBFS), Balance, 3D HRTF Spatializer, and Headphone Crossfeed.
- **DSD64 & DSD128 Native Browser Decoder:** Pure-JavaScript Blackman-windowed FIR low-pass decimation of `.dsf` and `.dff` 1-bit PDM streams to 88.2 kHz / 24-bit stereo WAV.
- **ITU-R BS.1770-4 K-Weighted LUFS & ReplayGain:** Reads ID3v2 `TXXX` and FLAC `VORBIS_COMMENT` ReplayGain tags; falls back to 2-stage K-weighted LUFS analysis targeting -14 LUFS / -1 dBTP.
- **PC & Browser Audio Capture:** Select USB audio interfaces, Line-In, virtual loopback drivers (BlackHole, VB-Cable, Stereo Mix), or OS screen/system audio, with anti-feedback Monitor Mute (`MON: MUTE`) and live `.webm` DSP recording (`REC`).
- **Full-Chain 24-bit Offline WAV Export:** Renders the complete DSP chain via `OfflineAudioContext`.
- **Self-Hosted Navidrome / Subsonic Streaming:** Salted MD5 token authentication (`t` + `s` parameters).
