Four-track recording on cassette
Gazillion Industries ·
In January 1982 a man recorded a set of demos at home on a four-track
cassette machine, carried the tape around in his jacket pocket with no case, and released it as
the album that September because nothing they cut in a studio sounded as right.
A four-track cassette recorder puts four separate mono tracks on a standard cassette by using
the full width of the tape in one direction, instead of two stereo pairs in two directions.
Each track has its own record-enable, level and pan, so you can record parts one at a time and
mix them down afterward. When you run out of tracks, you bounce: combine two or three of them
onto a spare track and reuse the ones you freed.
The short version
- How
- four mono tracks across the tape, one direction only
- Speed
- many machines ran at double cassette speed for more top end
- Bouncing
- combine tracks onto a spare one to free them up
- Cost
- each bounce adds a generation of noise and loses top
- Plan
- decide the bounce order before you record anything
- Mixdown
- out of the machine into a stereo recorder, in real time
How four tracks fit on a cassette
A normal cassette holds four tracks already: two for each side, so the tape can be flipped.
A four-track machine ignores the flip and records all four in one direction at once, which is
why a four-track tape played in a normal deck gives you your song with two parts backwards
underneath it. Many of these machines also ran the tape at twice the standard speed, which
extends the top end and halves your recording time.
Tape speed explains that trade.
How to work on four tracks
- Plan the song backwards: decide which parts will end up bounced together.
- Record the rhythm part to track one, with a click or a drum machine if you want a grid.
- Record the next two parts to tracks two and three, listening to track one.
- Set the balance of tracks one, two and three exactly as you want them for good.
- Bounce those three to track four in one pass.
- Erase tracks one to three and record three new parts over them.
- Repeat until the song is done or the noise becomes the song.
- Mix down to a stereo recorder in real time, riding the faders as it plays.
TRIPLE OG
is a cassette transport with AGE in years and a DRIVE that gets dirtier without getting louder,
which is most of what a bounced four-track pass was doing to your parts.
What bouncing costs
Every bounce is another generation of tape: more hiss, less top end, more saturation, and a
balance you can no longer change. Three parts bounced to one are married for life, and if the
guitar is too loud you re-record all three. Producers planned around that by recording the
things they were sure about first, and it is why home four-track records have a particular
layered haze on the early parts and a bright, present vocal sitting on top: the vocal was last,
so it was never bounced.
The noise is cumulative in a specific way. Each pass adds the machine's own hiss to the hiss
already on the tape, so by the third generation the quiet parts have a texture of their own.
Plenty of people spent the eighties fighting that and plenty of people now pay for it.
Doing it now
You can impose the same discipline in a DAW, and it is a better exercise than it sounds:
limit yourself to four tracks, and every time you want a fifth, bounce three to one and commit.
You get decisions instead of options, and arrangements that breathe because there was no room
for the extra part. Run each bounce through tape processing if you want the generational loss as
well as the constraint. See how to record to
cassette for the real version.
Where it costs you
Four tracks is four tracks. There is no undo, no punch-in that does not overwrite, no
rearranging the verse after the fact, and a mistake in bar 30 of a bounce means doing the whole
bounce again. Machines vary in speed, so a tape started on one deck may not finish on another.
And the tape runs for the length of a side: songs that need eight minutes need a plan.
Questions people ask
How does a multitrack recorder work?
It divides the recording medium into separate lanes and gives each one its own record and
playback path, so parts can be recorded at different times and balanced afterward. On a cassette
four-track, the four lanes are the four tracks the tape already has, used in one direction.
How do you record with a four-track cassette recorder?
Record one part per track while listening to what is already down, bounce finished parts
together onto a spare track when you run out, and mix the result to a stereo recorder in real
time.
Which classic albums were recorded on a four-track cassette?
Bruce Springsteen's "Nebraska" is the famous one: recorded at home in New Jersey in January
1982 on a four-track cassette machine and released that September as the demos themselves. The
format also carried a great deal of lo-fi indie rock and early home hip hop through the eighties
and nineties.
Why do four-track recordings sound like that?
Limited top end, a raised noise floor, gentle saturation from hitting the tape hard, and
generational loss from bouncing, all on a transport whose speed is never perfectly steady.
What TRIPLE OG does
TRIPLE OG is a cassette transport: six controls for what the medium is and what it is doing,
and one for your hand. AGE is in years, nought to sixty, and takes the machine
darker, noisier, slightly more saturated, less speed-stable and less perfectly matched left to
right at once. HISS is a continuous broadband bed, shaped and partly
decorrelated across the channels. DRIVE is soft asymmetric saturation,
oversampled, and the level stays flat inside half a decibel from one end of the knob to the
other.
No case on the cassette, in a jacket pocket, all the way to the pressing plant.
