“Clear voice. Anywhere.”
Salo made the sound of the early mobile phone — not the handsets, but the voice inside them: the codec subsystems, the comfort-noise generators, the network-test units carriers used to simulate a call falling apart. During the GSM boom its gear sat in every Nordic carrier's test lab. When voice moved to software codecs, the market for dedicated hardware closed; Salo was folded into a larger telecom concern and wound down around 2004. Orrery acquired its algorithm sources and a pallet of surviving test units, and models the codecs bit-for-bit from them — including the parts that sound broken, because to Salo, broken was the assignment.

OR-0023
3310 — Full-Rate GSM Codec
The everyday voice of 90s GSM: the watery, half-swallowed, faintly robotic sound of a mobile call, and the workhorse of the whole Salo line.
Issued without charge — the archive’s study copy.
OR-0024
8210 — TDMA Buzz
The flagship, and the most recognizable artifact of the era: the "da-da-da—dun-dun-dun" interference a GSM handset induced into nearby speakers and guitar pickups.
OR-0025
5110 — Frame Erasure / Dropped Call
The dying call: the robotic freeze, the underwater warble, then silence, as the network loses frames.
OR-0026
6150 — Adaptive Rate (AMR)
One knob labelled in signal bars.
OR-0027
8110 — Comfort Noise (DTX)
The eerie one.
OR-0028
2110 — POTS Telephone
The landline anchor and the oldest voice in the house — narrowband, companded, with dial tone in its bones.
OR-0029
3210 — Monophonic Ringer
The pre-polyphonic ringtone: a single tinny voice picking out a melody through a piezo buzzer — the sound of a phone in 1994.
OR-0030
3510 — Polyphonic Ringtone
The next generation — a handful of cheap FM voices playing a MIDI-style ringtone through a slightly-better-but-still-tiny speaker.
OR-0031
5610 — Dial-Up Modem
The sound of getting online: the dial, the carrier tones, and the scrambled training screech of a 56k handshake.
OR-0032
6210 — Vocoder
The classic robot voice, from the house that owned the codecs.
OR-0033
6310 — Speakerphone
The half-duplex speakerphone: the pumping echo-canceller and the voice-switching that clips whoever's quieter when both people talk at once.
OR-0034
2170 — Answering Machine
"You have one new message." Microcassette or early-digital voicemail grunge — narrowband, companded, and worn.
