What it does

Audio codec with HulyaPulse quantization. Zeqond-aligned frame encoding, perceptual masking model, variable bitrate targeting MUSHRA ≥85 at minimal bandwidth.

Signature

Request

POST /api/audio/codec

Param	Type	Required	Default	Description
audioData	object	✓	—	PCM audio to encode.
targetBitrate_kbps	number		128	Target bitrate.
mode	string		"zeq-adaptive"	'cbr', 'vbr', 'zeq-adaptive'.

Response

{ encodedData, actualBitrate_kbps, mushra_score, latency_ms, zeqond }

Runnable example

curl -sS -X POST \
  -H "Authorization: Bearer $ZEQ_API_KEY" \

  -d '{
  "audioData": {},
  "targetBitrate_kbps": 128,

Integrate

1. Domain solver — compose with KO42 + two additional operators from the matching family for pulse-coherent results.
2. Digital twin — pipe sensor data into this protocol every Zeqond to keep the model phase-locked with the system.
3. Alert threshold — flag results whose error_pct exceeds 0.1% as out-of-spec events for the operations layer.

Seeds

• Near — wrap /api/audio/codec in a language SDK so builders can call it in three lines.
• Medium — publish a reference integration demonstrating ZeqCodec alongside a real workload, with pulse-aligned metrics.
• Far — propose ZeqCodec as an open reference standard so other runtimes can implement it verbatim against the Zeq paper.
