Getting a 422 UNPROCESSABLE ENTITY when pushing the monitorPayload to the audio engine. The client engine throws a schema mismatch on the channelId reference inside the AudioInputMonitor object.
{
"error": "SchemaValidationError",
"message": "Invalid monitor schema: channel reference missing or threshold matrix out of bounds",
"details": {
"field": "monitorConfig.audioInputLevels",
"value": { "channelId": "primary_mic", "samplingIntervalMs": 500 }
}
}
We’re trying to hook up the C# client SDK to track input levels for the speech analytics pipeline. The code constructs the payload using MonitorService.CreateAudioMonitorRequest, but the engine rejects the decibelThresholdMatrix definition.
var monitorReq = new AudioMonitorRequest
{
ChannelId = "primary_mic",
SamplingInterval = TimeSpan.FromMilliseconds(500),
Thresholds = new DecibelMatrix { Min = -60, Max = 0 },
MaxDuration = TimeSpan.FromMinutes(10),
MuteDetection = true
};
The docs mention atomic control operations for level sampling, but the SDK wrapper seems to strip the formatVerification flag during serialization. We need the noiseFloorVerification pipeline to run before the webhook callback fires. Without that, the audit log is full of false mute events. The latency tracking shows the capture success rate drops when the buffer checking hits the max duration limit during Client scaling. We’ve got external audio diagnostics waiting on the webhook alignment for input governance.
