音频buffers被释放

Error message

音频buffers被释放

What it means

Recorder-Core's stop() found recSize > 0 but This.buffers[0] is missing, meaning the accumulated PCM buffer store was cleared (or never held) — typically because buffers were released after a previous stop or clear, or recording state and buffer store got out of sync.

Solutions

1. Don't call stop() twice; disable the stop button after the first invocation.
2. Only call stop() while the recorder is in a recording state (check rec.state).
3. Avoid manually mutating rec.buffers; rely on library APIs (start/stop/close).
4. After close(), recreate or re-open the recorder instead of stopping again.
5. If streaming with takeoffEncodeChunk, don't also expect stop() to return a full blob.

Example fix

// before
rec.stop();
rec.stop(); // second call: buffers released

// after
var stopped = false;
stopBtn.onclick = function() {
  if (stopped || rec.state !== 1) return;
  stopped = true;
  rec.stop(function(blob) { upload(blob); });
};

function canStopSafely(rec) {
  return rec && rec.state === 1 && rec.recSize > 0 && rec.buffers && rec.buffers[0];
}
if (!canStopSafely(rec)) return;

function buffersAvailable(rec) { return Array.isArray(rec.buffers) && rec.buffers.length > 0 && !!rec.buffers[0]; }

try { rec.stop(cb); } catch (e) {
  if (String(e).includes('音频buffers被释放')) resetRecorder();
}

When it happens

Trigger: rec.stop() invoked when recSize is nonzero but This.buffers[0] is undefined/falsy, i.e. the buffer array was emptied (e.g. rec.close() or buffer release happened) while recSize was not reset, or a second stop() raced the first.

Common situations: Double-invoking stop(); calling stop() after close() with stale size counters; using takeoffEncodeChunk where buffers are consumed/streamed and then released; manual buffer manipulation by application code.

Understand the failure class

Background: "Invalid state transition" errors: "status must be X, actually Y", "already rejected/charging/uninstalled", "cannot ... while running" — what they mean when a library rejects your call — this error's family across 31 libraries.
