ElevenLabs audio exceeds the 50 MB limit

Error message

ElevenLabs audio exceeds the 50 MB limit

What it means

ElevenLabsMusicError raised by _stream_audio while downloading the generated track: cumulative bytes crossed MAX_GENERATED_AUDIO_BYTES (50 MB, app/services/elevenlabs_music.py:24). The download is chunked at 1 MB precisely so an abnormally large or endless response is cut off early instead of filling the disk. The temp audio file (created via mkstemp in the output dir) is left for the caller's cleanup path.

Solutions

Retry once — oversized responses from a generation glitch are rare and transient.
Shorten the source video / music prompt so the generated track is smaller (cost scales with duration).
If it reproduces consistently, capture response headers (Content-Type/Content-Length) to see whether the API started returning WAV or duplicated bodies, and report upstream.

Defensive patterns

Strategy: retry

Try / catch

try:
    generate_bgm(video_path, output_path, prompt)
except ElevenLabsMusicError as e:
    if 'exceeds the 50 MB limit' in str(e):
        time.sleep(3)
        generate_bgm(video_path, output_path, shorter_prompt_or_trimmed_video)

Prevention

Keep source videos and prompts modest — generated track size scales with duration.
Retry once before escalating; oversized responses are usually one-off glitches.
If reproducible, inspect Content-Type/Length of the music response for API behavior changes.

When it happens

Trigger: The Music endpoint responding with an audio stream larger than 50 MB — e.g. an extremely long prompt-generated track, a WAV instead of compressed MP3, or a malformed/looping response body.

Common situations: Very long video durations producing long tracks; API behavior changes returning uncompressed audio; a proxy or retry layer duplicating the body.
