未采集到录音

Error message

未采集到录音

What it means

Recorder-Core's stop() checks This.recSize before encoding and errors when zero audio data was collected — the recorder ran (or was asked to stop) but never accumulated any PCM samples, so there is nothing to encode.

Solutions

1. Wait until onProcess has delivered data (or a small delay) after start() before calling stop().
2. Verify the microphone device is present, unmuted, and permission granted.
3. Ensure start() was called in a user-gesture handler so AudioContext is running.
4. Check rec.state and recSize before stop: only stop when recSize > 0.
5. If streaming chunks via takeoffEncodeChunk, remember data leaves via the worker path and stop-time size checks may legitimately see zero.

Example fix

// before
rec.start();
rec.stop(); // error: no samples yet

// after
rec.start();
setTimeout(function() {
  if (rec.recSize > 0) rec.stop();
}, 1000);

function safeStop(rec, cb) {
  if (!rec || rec.recSize === 0) { showToast('No audio captured'); return; }
  rec.stop(cb);
}

function hasAudioData(rec) { return !!rec && rec.recSize > 0; }

rec.stop(function(blob) { ... }); // plus pre-check:
if (!hasAudioData(rec)) { showToast('未采集到录音，请重新录制'); return; }

When it happens

Trigger: rec.stop() is called when This.recSize is 0, i.e. no onProcess buffers arrived: start() was never effective, capture was stalled, or stop happened before the first audio chunk.

Common situations: Calling stop() immediately after start() (same tick); microphone captured silence due to a muted/disconnected device while frames never flushed; browser suspended audio processing without a user gesture; isMock environment without a processing env configured.
