Tapes

YOUR MUSIC BELONGS TO YOU, NOT A SERVER. Tapes is the professional audio workspace built for the era of leaks and subscription fatigue. We believe you shouldn’t have to pay monthly rent just to organize your own files on your own device. Designed for producers, songwriters, hobbyists, and audio engineers, Tapes is a completely offline, privacy-first vault for your unreleased music. - No Uploads - No Buffering - No Cloud Storage Limits --- THE "LOCAL-FIRST" ADVANTAGE Most audio apps force you to upload gigabytes of data to their cloud, charging you for storage you already have on your phone. Tapes works differently. We unlock the power of your device’s local storage. - Zero Latency: Files open instantly. No "Downloading..." spinners. - Total Privacy: Your unreleased beats never leave your device. - Works Offline: Perfect for flights, subways, and studios with no reception. --- ON-DEVICE AI STEM SPLITTER Need to check a mix or write a verse over an instrumental? - Isolate Stems: Instantly separate Vocals, Drums, Bass, and Other instruments. - No Data Usage: Our AI runs on your phone’s Neural Engine, not a server. - Leak-Proof: Since you never upload the file, your stems remain 100% secure. --- PROFESSIONAL FILE MANAGEMENT Stop scrolling through a messy "Files" app or a chaotic Camera Roll. - Unlimited Tapes: Create as many project folders as you need. No arbitrary "5 project limit." - Format Freedom: Full support for WAV, MP3, AIFF, M4A, FLAC, and ZIP. - Drag & Drop: Import beats directly from iMessage, WhatsApp, or AirDrop. - Smart Search: Find any demo instantly by sound, melody, or key. --- BUILT FOR WORKFLOW - Visual Waveforms: See the music. Scrub with precision. - Loop Mode: Write verses on repeat without resetting the track. - Audio Denoiser: Clean up rough voice memos with one tap using local DSP. - Zip Export: Send a full project (beats + stems) to a collaborator in a single secure package. --- WHY WE BUILT TAPES The music industry runs on "Work in Progress," but the tools we use either feel like toys or charge us like enterprise software. Tapes is the middle ground: a utility knife for audio that respects your wallet and your data. Whether you have 10 demos or 10,000 archived sessions, Tapes handles it all without slowing down. Download Tapes today and own your workspace. --- Legal: Tapes processes audio locally. Performance depends on device capabilities. Always back up your data.
