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}")

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

const createRes = await fetch("https://api.audioshake.ai/tasks", {
  method: "POST",
  headers,
  body: JSON.stringify({
    assetId: "your_asset_id",
    targets: [
      { model: "guitar", formats: ["wav"], residual: true }
    ]
  })
});

const { id: taskId } = await createRes.json();
console.log(`Task created: ${taskId}`);

curl -X POST "https://api.audioshake.ai/tasks" \
  -H "Content-Type: application/json" \
  -H "x-api-key: $AUDIOSHAKE_API_KEY" \
  -d '{
    "assetId": "your_asset_id",
    "targets": [
      { "model": "guitar", "formats": ["wav"], "residual": true }
    ]
  }'
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
