The voices are still
on the tape

Halfspeed is an analog memory recovery bench. We bake, wind, calibrate and transfer the cassettes your family forgot — one reel at a time, nothing lost past the break.

Four turns of the reel

·HS-002 the bench process

Every cassette moves through the bench the same way it moves through a deck: assessed, conditioned, aligned, captured. The phosphor well marks where your reel is right now.

1

Assessment

We open the shell under the loupe, read the stock notches, smell for cellar damp and check the pad spring. Every observation goes in the ledger before the first wind.

day one · no power applied
2

Conditioning

Sticky-shed tapes bake at 48°C until the binder sets. Snapped leaders are spliced with fresh stock. Mouldy reels sit in quarantine until they are safe to thread.

six hours to five days
3

Calibration

The deck's azimuth is trimmed against a 10 kHz reference for your specific tape — a few minutes of arc is the difference between mud and a voice in the room.

Capture

One real-time pass at 24-bit/96 kHz, monitored off tape. A checksum seals the file, the ledger closes, and you get the audio plus our full bench notes.

What comes back

·HS-003 recovered material

Two hundred seventeen reels have crossed the bench. These are the kinds of things that were waiting on them.

kitchen tapes

Breakfast, 1976

A recorder left running on the table: cutlery, a radio, your grandmother telling a story she never wrote down.

nine c-90s · turku

answering machines

Messages kept too long

Micro-cassettes with the last voicemail someone ever left. We handle these first, and we handle them slowly.

splice queue priority

field recordings

The choir in the crypt

Rehearsals, sermons, shortwave loggings, a street market in 1988 — sound that exists nowhere else on earth.

"…and then your father carried the bicycle all the way up the hill, because the chain — no, wait, the tape, is it running? Is it running now?"

Marta Ojanen's mother, breakfast table, spring 1976. Recovered after nineteen winters in a garage.
