List available Gaudio AI models. Filter by category: 'stem' (instrument separation), 'dme' (dialogue/music/effects separation), 'text_sync' (lyrics sync).

Upload a local audio/video/text file to Gaudio servers. Handles multipart upload automatically (create → chunk upload → complete). The returned uploadId is valid for 72 hours and can be reused across multiple jobs. Supported formats: WAV, FLAC, MP3, M4A, MOV, MP4, TXT.

Create a processing job with an uploaded file. For Stem Separation models (gsep_music_hq_v1, gsep_music_shq_v1, gsep_speech_hq_v1), the 'type' parameter is required (e.g. 'vocal', 'vocal,drum'). For DME models, no type is needed. For Text Sync (gts_lyrics_line_v1), use gaudio_sync_lyrics instead.

Check job status and get results. Status: 'waiting' (queued), 'running' (processing), 'success' (done, downloadUrl included), 'failed' (error). Download URLs expire after 48 hours.

All-in-one audio separation: upload file (or reuse uploadId) → create job → poll until done → return download URLs. For Stem Separation, provide 'type' (e.g. 'vocal', 'vocal,drum'). For DME Separation, no type needed. Supports WAV, FLAC, MP3, M4A, MOV, MP4.

All-in-one lyrics sync: upload audio + text files → create gts_lyrics_line_v1 job → poll → return CSV (timestamp, lyric_text, confidence_score) + JSON report URLs. Text file requirements: .txt format, UTF-8, minimum 2 lines, max 60 characters per line. Audio limit: 1GB / 10 minutes.
