Build practice and jam-along experiences by removing a single instrument from a song. Use the residual option to get everything except the target instrument — perfect for guitarists, bassists, drummers, or any musician who wants to play along with the rest of the band.

​
Create a Task

This example removes the guitar from a track. The residual: true flag returns everything except the guitar — your ready-to-use backing track: 
import requests

API_KEY = "your_api_key"
HEADERS = {"Content-Type": "application/json", "x-api-key": API_KEY}

response = requests.post(
    "https://api.audioshake.ai/tasks",
    headers=HEADERS,
    json={
        "assetId": "your_asset_id",
        "targets": [
            {"model": "guitar", "formats": ["wav"], "residual": True}
        ]
    }
)

task_id = response.json()["id"]
print(f"Task created: {task_id}")
Check Task status to monitor progress and download results, or use webhooks to be notified when each target completes. With residual: true, you get two outputs — the isolated instrument and the residual (everything else). Use the residual as the backing track.

Try other instruments

Swap the model to create practice tracks for any instrument:
ModelPractice scenario
guitarGuitar play-along
bassBass play-along
drumsDrum play-along
pianoPiano / keys play-along
vocalsVocal practice / sing-along
