## AI Music Generation
Generate songs, rap, instrumentals, samples, and vocals from text prompts.
**Tasks:** `text2music` (song with vocals), `text2rap` (rap), `prompt2instrumental` (instrumental), `lyric2vocals` (vocals only), `text2samples` (loops/samples), `audio2audio` (style transfer), `songbloom`
### Python SDK
```python
# Generate a full song with lyrics
result = client.music.song(
prompt="Upbeat pop, synth, drums, 120 bpm, female vocals, radio-ready",
lyrics="Verse 1:\nWalking down the street on a sunny day\n\nChorus:\nWe're on fire tonight!",
duration=60
)
print(result["output_url"])
# Generate rap
result = client.music.rap(
prompt="Lo-Fi Hip Hop, 100 BPM, male rap, melancholy, keyboard chords",
lyrics="Verse 1:\nStarted from the bottom, now we climbing...",
duration=60
)
# Generate instrumental (no lyrics needed)
result = client.music.instrumental(
prompt="Atmospheric ambient soundscape, uplifting, driving mood",
duration=30
)
# Generic generate with explicit task
result = client.music.generate(
prompt="Electronic dance music, high energy",
task="text2samples", # any task type
duration=30
)
# Async: submit then poll
job = client.music.create(
prompt="Chill lofi beat",
duration=30,
task="prompt2instrumental"
)
result = client.music.wait_for_completion(job["id"], timeout=600)
# Get available genre presets

# List/manage jobs
jobs = client.music.list(skip=0, limit=50)
job = client.music.get(job_id=123)
client.music.delete(job_id=123)

## Text to Speech
Generate speech from text with 50+ voices in 60+ languages. Supports voice cloning.
### Voice Types
- **50+ production-ready voices** — multilingual, supporting 60+ languages with auto-detection
- **Custom clones** — clone any voice with ~5 seconds of audio sample
### Python SDK
```python
# Generate speech and wait for result
result = client.voice.generate(
text="Hello, world! This is a test.",
voice_id=123,
speed=1.0
)
print(result["output_url"])
# Async: submit then poll
job = client.voice.speak(
text="Hello world",
voice_id=123,
speed=1.0
)
status = client.voice.get_job(job["id"])
result = client.voice.wait_for_completion(job["id"], timeout=300)
# List all available voices
voices = client.voice.list()
for v in voices:
print(f"{v['id']}: {v['name']}")
# Clone a voice (needs ~5 sec audio sample)
new_voice = client.voice.create(
name="My Voice Clone",
audio_file="./sample.mp3",
description="Cloned from recording"
)
# Get/delete voice
voice = client.voice.get(voice_id=123)
client.voice.delete(voice_id=123)
```
### cURL (Raw HTTP — most reliable)
```bash
# List all voices
curl "https://api.audiopod.ai/api/v1/voice/voice-profiles" \
-H "X-API-Key: $AUDIOPOD_API_KEY"
# Generate speech (FORM DATA, not JSON!)
curl -X POST "https://api.audiopod.ai/api/v1/voice/voices/{VOICE_UUID}/generate" \
-H "Authorization: Bearer $AUDIOPOD_API_KEY" \
-d "input_text=Hello world, this is a test" \
-d "audio_format=mp3" \
-d "speed=1.0"
# Poll job status
curl "https://api.audiopod.ai/api/v1/voice/tts-jobs/{JOB_ID}/status" \
-H "Authorization: Bearer $AUDIOPOD_API_KEY"
# SDK-style endpoints (alternative)
# Generate via SDK endpoint
curl -X POST "https://api.audiopod.ai/api/v1/voice/tts/generate" \
-H "X-API-Key: $AUDIOPOD_API_KEY" \
-H "Content-Type: application/json" \
-d '{"text":"Hello world","voice_id":123,"speed":1.0}'
# Poll via SDK endpoint
curl "https://api.audiopod.ai/api/v1/voice/tts/status/JOB_ID" \
-H "X-API-Key: $AUDIOPOD_API_KEY"
# List voices (SDK endpoint)
curl "https://api.audiopod.ai/api/v1/voice/voices" \
-H "X-API-Key: $AUDIOPOD_API_KEY"
# Clone a voice
curl -X POST "https://api.audiopod.ai/api/v1/voice/voices" \
-H "X-API-Key: $AUDIOPOD_API_KEY" \
-F "name=My Voice" \
-F "file=@sample.mp3" \
-F "description=Cloned voice"
# Delete voice
curl -X DELETE "https://api.audiopod.ai/api/v1/voice/voices/VOICE_ID" \
-H "X-API-Key: $AUDIOPOD_API_KEY"
```
### Generate Parameters
| Field | Required | Description |
|-------|----------|-------------|
| input_text | yes | Text to speak (max 5000 chars). Use `input_text` for raw HTTP, `text` for SDK |
| audio_format | no | mp3, wav, ogg (default: mp3) |
| speed | no | 0.25 - 4.0 (default: 1.0) |
| language | no | ISO code, auto-detected if omitted |
### Response Format
```json
// Generate response
{"job_id": 12345, "status": "pending", "credits_reserved": 25}
// Status response (completed)
{"status": "completed", "output_url": "https://r2-url/generated.mp3"}
```
### Important Notes
- Raw HTTP generate endpoint uses **form data**, not JSON. Field is `input_text` not `text`
- SDK endpoint (`/api/v1/voice/tts/generate`) uses JSON with field `text`
- Output files may be WAV disguised as .mp3 — convert with `ffmpeg -i output.mp3 -c:a aac real.m4a`
- ~55 credits per generation, wallet-based billing

## Speaker Separation
Separate audio by speaker with automatic diarization.
### Python SDK
```python
# Diarize and wait for result
result = client.speaker.identify(
file="./meeting.mp3",
num_speakers=3, # optional hint for accuracy
timeout=600
)
for segment in result["segments"]:
print(f"Speaker {segment['speaker']}: {segment['text']} [{segment['start']:.1f}s - {segment['end']:.1f}s]")
# From URL
result = client.speaker.identify(
url="https://youtube.com/watch?v=VIDEO_ID",
num_speakers=2
)
# Async: submit then poll
job = client.speaker.diarize(
file="./meeting.mp3",
num_speakers=3
)
result = client.speaker.wait_for_completion(job["id"], timeout=600)
# Job management
jobs = client.speaker.list(skip=0, limit=50, status="COMPLETED")
job = client.speaker.get(job_id=123)

## Auth Headers
Two auth styles work:
- `X-API-Key: ap_...` — works for most endpoints
- `Authorization: Bearer ap_...` — works for TTS generate/status
## Known Issues
- SDK method signatures may differ from raw API — when in doubt, use cURL examples
- TTS output stored on Cloudflare R2, download via `output_url` in job status
- TTS output files may be WAV disguised as .mp3 — convert with ffmpeg before sending via WhatsApp
