How to record vinyl to a Mac
Tested on macOS 26.4.1 (Tahoe), Apple M3 Max, 3 Sept 2026. Updated 2026-09-03.
You record vinyl to a Mac by passing the turntable through a phono preamp (built into the turntable, a receiver, a DJ mixer, or a separate box) and then into the line inputs of a USB audio interface, or by using a USB turntable. A moving magnet cartridge puts out about 5 mV; a phono stage raises that roughly 100 times and applies RIAA equalization. Record 24-bit, split tracks afterwards.
Why does a turntable need a phono preamp before the Mac?
Two reasons, both physical. First, level: a moving magnet cartridge delivers a nominal 5 mV, and a phono stage with the standard 40 dB of gain at 1 kHz turns that into about 500 mV, roughly line level. A line input fed directly from a cartridge records a whisper buried in noise. Second, equalization: records are cut with the RIAA curve, bass reduced and treble boosted, and the phono preamp applies the inverse curve on playback. Skip it and the recording is thin, bright and quiet even after normalizing.
You already have a phono stage if any of these is true:
- The turntable has a PHONO/LINE switch or a built-in preamp (some current models do).
- You play through a DJ mixer with PHONO inputs; take the mixer's REC or MASTER out.
- The turntable is a USB model, which has the preamp and the A/D converter built in.
Otherwise buy a small MM phono preamp and put it between the turntable and the interface. Connect the turntable's ground wire to the preamp's ground post; a loud hum at 50 or 60 Hz is nearly always a missing ground.
What goes between the preamp and the Mac?
A Mac has no line input. Current MacBooks have a headphone jack only, so you need one of three things:
- USB turntable. Plug it in; it appears in System Settings > Sound > Input as a stereo device. Simplest, fixed quality, no level control.
- USB audio interface with line inputs. Preamp output (RCA) into two line inputs with RCA to 1/4 inch cables. A Scarlett 2i2 4th Gen ($224.99) accepts line signals on its two front combo jacks; a Scarlett 4i4 4th Gen ($309.99) adds rear line inputs so the mic preamps stay free. All run at 44.1 or 48 kHz up to 192 kHz, 24-bit.
- DJ mixer with a USB sound card that sends its master back over USB. Same result as an interface.
Whichever you use, select that device and the correct channel pair in the recorder. On a multi-input interface the vinyl may be on inputs 3-4 while the recorder defaults to 1-2; the fix is in record a DJ mix with an audio interface. The buying decision for interfaces is in which audio interface you need.
What level, bit depth and sample rate should vinyl be recorded at?
Vinyl has a wider crest factor than a mastered DJ mix: clicks and loud transients peak far above the average. Set the level on the loudest passage of the loudest side, with peaks around -6 dBFS, and leave room for the pops. Record 24-bit so that headroom is free; you normalize the whole side once afterwards. Recording 16-bit with peaks at -12 dBFS throws away resolution you cannot get back.
Sample rate: 44.1 kHz or 48 kHz. A 96 kHz file doubles the size for a difference most listeners cannot hear on a record. Measured on the author's Mac, 24-bit 48 kHz is 16.5 MB per minute and 24-bit 44.1 kHz is 15.1 MB per minute. A 20 minute LP side is therefore about 330 MB at 48 kHz or 300 MB at 44.1 kHz; a full album about 650 MB as a 24-bit master, or 96 MB as MP3 320 kbps (2.4 MB per minute). Details in how big is an audio recording per minute.
Record one side as one take. Do not stop between tracks; you lose the run-in and it doubles the work.
How do you split a vinyl recording into tracks?
Record the side as a single file, then split it. A dedicated recorder like AirCheck does not edit, so use a free editor for the cut: Audacity (free) with Edit > Labels > Add Label at each gap, then File > Export > Export Multiple, or any DAW with markers. Cut in the silence between tracks, not at the first transient, and keep the run-in groove noise on the first track rather than a hard silence.
Automatic silence detection is unreliable on vinyl because the groove noise between tracks is not silence and quiet intros are. Set the labels by ear at 1x speed; a 20 minute side takes 20 minutes and is right.
Export the split tracks as 16-bit WAV or FLAC for a library, or MP3 320 kbps for the phone, and keep the 24-bit side master in case you want to declick it later. Name the files with track numbers so the album sorts correctly.
A phono preamp is a device that amplifies the signal from a turntable to a level that can be processed by a standard audio system.

Where AirCheck fits
AirCheck ($39, macOS 14 or newer) records any Core Audio input, so a USB turntable, an interface, or a mixer's USB return all show up in its device list, with a channel-pair picker when the vinyl sits on inputs 3-4. It captures 24-bit at the device rate and exports WAV 16-bit, WAV 24-bit or MP3 320 kbps when the side ends. No length limit, no silence detection, no editing: you still split tracks in Audacity or a DAW afterwards.
When you do not need it: Audacity alone records a USB turntable or interface for free and can also split the tracks, so if you are digitizing a few records and are happy with its interface, you do not need a separate recorder.
AirCheck records what your Mac plays, or any input, to one file. $39 once.
macOS 14 or newer. One-off payment. Fourteen-day refund, no questions asked.
Questions people ask
How do I record vinyl to my MacBook?
Turntable, phono preamp (built in or separate), then a USB turntable, USB interface or USB mixer into the MacBook. Select that device in the recorder, set peaks around -6 dBFS on the loudest passage, record one side per take at 24-bit, then split the tracks.
Can I plug a turntable straight into a Mac?
No. A Mac has no line or phono input, and a cartridge's roughly 5 mV signal needs a phono preamp with RIAA equalization first. Use a USB turntable or a preamp plus a USB interface.
Does a USB turntable need a preamp?
No. A USB turntable contains the phono preamp and the analog to digital converter, and appears on the Mac as a USB audio input. What you give up is control over the recording level.
Why does my vinyl recording hum?
Usually the turntable's ground wire is not connected to the preamp or mixer ground post, or a switching power supply sits next to the tonearm cable. Connect the ground, move the supply, and retest before blaming the interface.
