SUNO! អញអោយស្ពៃ - Suno Music Downloader
Intercept Suno audio streams, decrypt HLS AES-128 & Mango DRM in-browser, and convert/download to MP3, WAV, or original M4A with split format dropdown.
About this script
A powerful in-browser music extraction and decryption userscript for suno.com built by Nisay Tech. Intercepts Suno's HLS playlists and Mango DRM audio streams, executes real-time AES-128-CBC and AES-CTR cryptographic decryption via Web Crypto, and converts audio client-side to universal MP3 (192kbps) or lossless WAV (16-bit PCM) via a split format selector dropdown right on the song cards.
Features
- M4A Default & Instant Stream: direct untouched stream download as default format with zero conversion delay.
- Fixed-Portal Dropdown: floating menu mounted directly to document.body (z-index 2147483647) - 100% immune to virtual list and row stacking issues.
- Client-Side MP3 Conversion: transcode decoded PCM audio directly in-browser to universal 192kbps MP3 via LAME encoder.
- Lossless WAV Conversion: instant 16-bit stereo PCM WAV encoding via native Web Audio API with zero external dependencies.
- In-browser AES-128 HLS Decryption: automatically stitches encrypted .ts/.m4a audio chunks using Web Crypto API.
- Mango DRM Decryption: handles Suno studio-api rights negotiation and AES-GCM / AES-CTR key derivation.
- Persistent Preference: remembers your chosen format (M4A / MP3 / WAV) across sessions.
- Zero external companion app required: operates 100% client-side in Tampermonkey and Violentmonkey.
