The @buape/carbon RequestClient wasn't setting Content-Type: application/json
for the attachments endpoint request. Use native fetch with explicit headers
for the upload URL request.
Also pass token through to sendDiscordVoiceMessage for authorization.
Adds support for sending Discord voice messages via the message tool
with asVoice: true parameter.
Voice messages require:
- OGG/Opus format (auto-converted if needed via ffmpeg)
- Waveform data (generated from audio samples)
- Duration in seconds
- Message flag 8192 (IS_VOICE_MESSAGE)
Implementation:
- New voice-message.ts with audio processing utilities
- getAudioDuration() using ffprobe
- generateWaveform() samples audio and creates base64 waveform
- ensureOggOpus() converts audio to required format
- sendDiscordVoiceMessage() handles 3-step Discord upload process
Usage:
message(action='send', channel='discord', target='...',
path='/path/to/audio.mp3', asVoice=true)
Note: Voice messages cannot include text content (Discord limitation)
