FourTrack: Cassette Recorder

FourTrack is a four-track cassette recorder for iPhone, iPad and Mac. It brings back the way songs used to start: press record, play your part, then layer the next one on top.

RECORD AND OVERDUB
• Four tracks, recorded one at a time or several at once
• Overdub against what you've already laid down, in time
• Punch in mid-song: press REC while the tape is rolling
• Every take is kept. Record over a part and the old take is still there underneath; remove the last take to bring it back
• Built-in latency calibration lines up new takes with the old ones on your exact headphones or interface

MIX LIKE A CONSOLE
• Volume, pan, mute and solo on every channel
• Three-band EQ (treble, mid, bass)
• One effect per channel: reverb (room, plate or hall), echo or chorus, with an amount knob
• VU meters and peak lights so you can see your levels

THE SOUND OF TAPE
• Master tape emulation: saturation, wow, flutter and hiss, with one Character knob to set the overall amount
• Two tape speeds: 1⅞ ips for a warm, worn sound and 3¾ ips for a cleaner one
• One-knob master compression from subtle glue to heavy squash, with a gain reduction meter
• A limiter on the output keeps your mix from clipping

SEE YOUR SONG
• Real waveforms on four lanes passing under the playhead, like tape passing the head
• Drag to wind the tape, pinch to zoom

FINISH IT
• Mix down to 24-bit WAV or AAC (M4A), with your tape and compression settings applied
• Share the mix or save it to Files
• Sessions save automatically; create, rename and switch between as many as you like

ON EVERY DEVICE
• iPhone, iPad (wide layout with the mixer beside your tracks) and Mac
• On Mac, choose your audio input and output devices

PRIVATE BY DESIGN
No account, no ads, no tracking. Your recordings stay on your device unless you choose to share them.

For the best results use wired or USB headphones while overdubbing. Bluetooth headphones add a delay that makes playing in time difficult.
