Technical Specifications (Hardware dependent) File formats: WAV / AIFF / CAF / M4A Sample rates: 44.1 / 48 kHz Bit depth: 8 / 16 / 24 / 32-bit float Channels: Mono + Stereo beamforming Filtering: ±12 dB high- and low-pass Pitch detection: Always on, built-in tuner Monitoring: Wired · Bluetooth Requires: iOS 17+, iPhone or iPad Made for everyday people who want to make the most of their iPhone's native recording capabilities, musicians capturing rehearsals, demos, and ideas, and sound designers & experimentalists chasing texture out in the wild or in the studio. Did you know your iPhone & iPad has multiple microphones with polarity patterns that are all available under the hood? This app accesses all of them. Select a mic and a polar pattern (mono only) or choose stereo recording in Settings. Monitoring starts at app launch, hit Record, add a marker if you hear something cool. Then play your recordings back, share them, and use them in your creations. Input gain is adjustable and you can push it to distort if you'd like. If you plug in wired headphones you can listen to your environment and what you're recording, there's plenty of extra monitoring gain there too if you need it. Bluetooth monitoring is also available with latency, but with noise cancelling enabled it works pretty well. All your recordings are stored on device and accessible in the Recordings page, where you can see any cue markers you've made, scrub through long recordings, rename the file, and share the file outside the app. Designed and Built in Northern California.

GCS Model 8 is a free, pocket-sized 8-track tape DAW for iPhone. It has a full blown physics engine which runs in the background and models classic reel-to-reel machines and various formats ranging from LoFi cassette to HiFi 1" tape. The engine is the exact same as the one used in the professional desktop recording version, but still runs very nicely on iPhone. GCS Model 8 for iPhone is completely free, with no in-app purchases, subscriptions, or ads. I really want people to have the engine as a fun tool for mobile settings without any sort of catch. Features: • 8-track recording with a real tape transport (play, record, rewind, fast-forward, punch, scrub) • Analog tape physics: adjustable wow, flutter, stickiness, head gap, hiss, and age • Built-in effects and tape techniques: reverse, SOS, punch, click track, loop • Built-in instruments: A-1 Mono Synth, A-10 Poly Synth, Glissandio (Ondes Martenot style slide synth), Stage Keyboard • Voxtone Drum Machine: synthesized analog drums with a dedicated step-sequencer (MATRIX) and live-trigger (PADS) view, plus two sample-based kits (808, Acetone) • 8-pad MPC-style Pad Sampler: load your own samples or mic them in directly, with pitch, trim, and gate controls • Reels: save, load, and share your sessions • Bluetooth MIDI keyboard support • Importing recordings to hit them to tape • Sound of Sound looping (Fripp style) • Formats: cassette, 1/4", 1/2" and 1" - along with various presets •Most of the features found on the desktop version Reels you create on iPhone move over to GCS Model 8 for iPad and GCS Model 8 for Mac/Windows, which add more tracks, more effects, and full export/mixdown for when you're ready to take a session further.
