BitPerfect

Welcome to BitPerfect! The ultimate, absolute, no-compromise, bit-obsessed CD ripping app for Android!

Are you tired of wondering if that scratch on track 4 of your rare Japanese import of Dark Side of the Moon ruined the audio? Do you lie awake at night sweating over drive read offsets and cache flushing? Well, grab your OTG cable and your favorite USB CD drive, because we're about to get BIT PERFECT!

What is this witchcraft?

BitPerfect is an Android app that lets you plug a USB CD/DVD drive directly into your phone or tablet and rip your precious silver discs to glorious, lossless FLAC format.

But wait, there's more! We don't just "rip" CDs like it's 2004. Oh no. We VERIFY them!

Features that will make your audiophile heart sing

- AccurateRip™ Integration: We check your rips against the legendary AccurateRip database (v1 & v2 algorithms!) to ensure your copy is mathematically identical to thousands of others. - Drive Capability Detection: We interrogate your USB drive like a '90s action hero. We find out if it supports Accurate Stream, C2 Error Pointers, and if it has a cache. - Cache Busting: Oh, your drive thinks it's smart by caching audio data? We do decoy reads to flush that cache and force the drive to actually read the disc during multi-pass secure reads. Take that, firmware! - Drive Offsets: We handle read offsets automatically. We even auto-calibrate! - Lossless FLAC Encoding: Encoded using Android's native MediaCodec for that sweet, sweet compression without losing a single zero or one. - Metadata Fetching: Because nobody wants to listen to Track01.flac. We fetch album art and tags so your library looks as good as it sounds. - USB OTG Magic: Just plug in your mass storage CD drive and watch the magic happen. - Storage Access Framework: Save your precious FLACs wherever you want—internal storage, SD card, or your secret audiophile vault.

How to use (The Ritual)

1. Get the app: Install BitPerfect on your Android device. 2. Get the hardware: Find a USB CD/DVD drive and an OTG (On-The-Go) adapter. 3. The Connection: Plug the drive into your phone. (Grant those USB permissions like a boss!) 4. The Offering: Insert a CD. 5. The Magic: Watch the app read the TOC (Table of Contents), fetch metadata, and prepare for extraction. 6. The Rip: Hit "Start Secure Rip" and watch the sectors fly by. 7. The Validation: Bask in the glory of the AccurateRip verification match.

For the Nerds (You know who you are)

Under the hood, BitPerfect speaks fluent SCSI commands (like READ TOC, TEST UNIT READY, and READ CD). We handle MMC-compliant ADR and Control parsing, MSF/LBA conversions, and we even have a virtual SCSI driver for testing!

If you speak Kotlin, Coroutines, and Ktor, you're going to love this codebase.

Now go forth and rip your CDs perfectly! Your ears will thank you.
