Frames are emitted progressively as audio is streamed. Real-time frame-level music and speech classification over WebSocket. Frames are returned progressively as audio is streamed — no need to wait for the full file to upload before results begin arriving. ## Endpoint ```text theme={null} wss://platform.modulate.ai/api/velma-2-music-detection-streaming ``` ## Authentication Pass your API key as a query parameter on the connection URL: ```text theme={null} wss://.../velma-2-music-detection-streaming?api_key=YOUR_API_KEY&audio_format=s16le&... ``` ## Features * **Real-time output** — frames emitted progressively after each 192ms chunk of audio * **Music detection** — identifies frames containing music content * **Speech detection** — identifies frames containing speech content * **Non-exclusive labels** — music and speech are independent; both can be high simultaneously (e.g. music with vocals) * **Any chunk size** — send audio in whatever chunk size suits your pipeline * **Container and raw PCM support** — stream compressed files or raw PCM directly from a microphone ## Connection parameters | Parameter | Required | Description | | - | - | - | | `api_key` | Yes | Your API key | | `audio_format` | Yes | Audio format — see supported formats below | | `sample_rate` | Raw PCM only | Sample rate in Hz | | `num_channels` | Raw PCM only | Number of channels (1–8) | ## Supported audio formats **Container formats** — `sample_rate` and `num_channels` are ignored if supplied (the headers already carry this metadata): `mp3`, `wav`, `flac`, `m4a`, `mp4`, `ogg`, `opus`, `webm`, `aac`, `aiff`, `wma`, `amr`, and `au`, plus 66 others `3g2`, `3ga`, `3gp`, `3gpp`, `8svx`, `aa3`, `aac`, `ac3`, `act`, `adts`, `aif`, `aifc`, `aiff`, `amb`, `amr`, `asf`, `at3`, `au`, `avr`, `awb`, `bwf`, `c2`, `caf`, `dss`, `dts`, `dtshd`, `eac3`, `ec3`, `f4a`, `f4b`, `flac`, `gsm`, `iff`, `m2a`, `m2ts`, `m4a`, `m4b`, `m4r`, `m4v`, `mka`, `mkv`, `mlp`, `mp+`, `mp1`, `mp2`, `mp3`, `mp4`, `mpa`, `mpc`, `mpga`, `mpp`, `mts`, `oga`, `ogg`, `ogx`, `oma`, `omg`, `opus`, `paf`, `pvf`, `qcp`, `ra`, `rf64`, `rm`, `rmvb`, `snd`, `svx`, `thd`, `ts`, `tta`, `voc`, `vqf`, `w64`, `wav`, `wave`, `weba`, `webm`, `wma`, `wmv` The MP4-family values (`mp4`, `m4a`, `m4b`, `m4r`, `m4v`, `3gp`, `3gpp`, `3ga`, `3g2`, `f4a`, `f4b`) must be sent in a streamable layout; otherwise the connection ends with an audio-processing error. **Raw PCM formats** — `sample_rate` and `num_channels` are required: `s8`, `s16le`, `s16be`, `s24le`, `s24be`, `s32le`, `s32be`, `u8`, `u16le`, `u16be`, `u24le`, `u24be`, `u32le`, `u32be`, `f32le`, `f32be`, `f64le`, `f64be`, `mulaw`, `alaw`, `g722`, `vox` `g722` and `vox` are mono-only: `num_channels` must be `1`. **Valid sample rates:** 8000, 11025, 16000, 22050, 32000, 44100, 48000, 96000 ## Protocol ### Client → server | Message | Description | | - | - | | Binary frame | Chunk of audio bytes in the declared format (any size) | | Empty text frame `""` | Signals end of stream | ### Server → client | Message | Description | | - | - | | `{"type": "frame", "frame": {...}}` | Frame result — emitted after each 192ms chunk | | `{"type": "done", "duration_ms": ..., ...}` | Stream complete — includes overall summary across all frames | | `{"type": "error", "error": "..."}` | An error occurred — connection will close | ### Frame object | Field | Type | Description | | - | - | - | | `start_time_ms` | integer | Frame start time in milliseconds | | `end_time_ms` | integer | Frame end time in milliseconds | | `music_prob` | float | Music probability (0.0–1.0) | | `speech_prob` | float | Speech probability (0.0–1.0) | ### Done object | Field | Type | Description | | - | - | - | | `duration_ms` | integer | Total audio duration processed in milliseconds | | `frame_count` | integer | Total number of frames returned | | `music_pct` | float | Percentage of the analysed duration classified as music, rounded to one decimal place. `0.0` when no audio was analysed | | `speech_pct` | float | Percentage of the analysed duration classified as speech, rounded to one decimal place. `0.0` when no audio was analysed | | `primary_label` | string | Dominant classification: `"music"`, `"speech"`, `"neither"`, or `"unknown"` (no frames produced from the audio) | ## WebSocket close codes | Code | Meaning | | - | - | | `1000` | Normal closure after a successful `done` message | | `1003` | Invalid query parameters (unknown format, bad sample rate, missing `audio_format`) | | `1011` | Internal server error | | `4001` | The `api_key` query parameter is missing or invalid | | `4002` | Audio could not be decoded or does not match the declared format | | `4003` | The request is not permitted | | `4004` | The API key does not have access to this model | | `4029` | Insufficient credits | | `4030` | Concurrent request limit reached | | `4031` | Monthly usage limit reached | ## Chunking behaviour Audio is buffered in 192ms chunks (one output frame each). Frames are emitted as soon as each chunk is ready, so results begin arriving within 192ms of the first audio being received. At end-of-stream, any remaining audio ≥ 192ms is processed and its frames are emitted before the `done` message. ## Examples ```python Python (raw PCM) theme={null} import asyncio import websockets import json WS_URL = "wss://platform.modulate.ai/api/velma-2-music-detection-streaming" API_KEY = "YOUR_API_KEY" async def stream_audio(file_path: str) -> None: url = ( f"{WS_URL}?api_key={API_KEY}" f"&audio_format=s16le&sample_rate=16000&num_channels=1" ) async with websockets.connect(url) as ws: # Send audio in chunks with open(file_path, "rb") as f: while chunk := f.read(16000): # 0.5s of s16le/16kHz mono await ws.send(chunk) # Signal end of stream await ws.send("") # Receive results async for message in ws: msg = json.loads(message) if msg["type"] == "frame": frame = msg["frame"] print( f"{frame['start_time_ms']}ms – {frame['end_time_ms']}ms " f"music={frame['music_prob']:.4f} speech={frame['speech_prob']:.4f}" ) elif msg["type"] == "done": print(f"\nDone — {msg['duration_ms']}ms, {msg['frame_count']} frames") print(f"music={msg['music_pct']}% speech={msg['speech_pct']}% label={msg['primary_label']}") break elif msg["type"] == "error": raise RuntimeError(f"Server error: {msg['error']}") asyncio.run(stream_audio("/path/to/audio.raw")) ``` ```python Python (container format) theme={null} import asyncio import websockets import json WS_URL = "wss://platform.modulate.ai/api/velma-2-music-detection-streaming" API_KEY = "YOUR_API_KEY" async def stream_audio_file(file_path: str, audio_format: str) -> None: url = f"{WS_URL}?api_key={API_KEY}&audio_format={audio_format}" async with websockets.connect(url) as ws: with open(file_path, "rb") as f: while chunk := f.read(65536): await ws.send(chunk) await ws.send("") async for message in ws: msg = json.loads(message) if msg["type"] == "frame": frame = msg["frame"] print( f"{frame['start_time_ms']}ms – {frame['end_time_ms']}ms " f"music={frame['music_prob']:.4f} speech={frame['speech_prob']:.4f}" ) elif msg["type"] == "done": print(f"\nDone — {msg['duration_ms']}ms, {msg['frame_count']} frames") print(f"music={msg['music_pct']}% speech={msg['speech_pct']}% label={msg['primary_label']}") break elif msg["type"] == "error": raise RuntimeError(f"Server error: {msg['error']}") asyncio.run(stream_audio_file("/path/to/audio.mp3", "mp3")) ``` ```javascript JavaScript (Node.js) theme={null} import { WebSocket } from "ws"; import { createReadStream } from "fs"; const WS_URL = "wss://platform.modulate.ai/api/velma-2-music-detection-streaming"; const API_KEY = "YOUR_API_KEY"; async function streamAudio(filePath, audioFormat) { const url = `${WS_URL}?api_key=${API_KEY}&audio_format=${audioFormat}`; const ws = new WebSocket(url); await new Promise((resolve, reject) => { ws.on("open", () => { const stream = createReadStream(filePath, { highWaterMark: 65536 }); stream.on("data", (chunk) => ws.send(chunk)); stream.on("end", () => ws.send("")); stream.on("error", reject); }); ws.on("message", (data) => { const msg = JSON.parse(data); if (msg.type === "frame") { const { start_time_ms, end_time_ms, music_prob, speech_prob } = msg.frame; console.log( `${start_time_ms}ms – ${end_time_ms}ms ` + `music=${music_prob.toFixed(4)} speech=${speech_prob.toFixed(4)}` ); } else if (msg.type === "done") { console.log(`\nDone — ${msg.duration_ms}ms, ${msg.frame_count} frames`); console.log(`music=${msg.music_pct}% speech=${msg.speech_pct}% label=${msg.primary_label}`); ws.close(); resolve(); } else if (msg.type === "error") { reject(new Error(`Server error: ${msg.error}`)); } }); ws.on("error", reject); }); } await streamAudio("/path/to/audio.mp3", "mp3"); ``` ## Rate limits * Concurrent connection limits apply per model ## AsyncAPI ````yaml api/velma_2_music_detection_streaming.yaml streaming-detection id: streaming-detection title: Streaming-detection description: | ## WebSocket Close Codes - `1000`: Normal closure after the `done` message, or after the connection completes. - `1003`: Invalid or missing query parameters (unknown `audio_format`, invalid `sample_rate` or `num_channels`, a raw format missing `sample_rate`/`num_channels`, `sample_rate`/`num_channels` supplied without `audio_format`, or `audio_format` omitted).
