Claude-specific workflow

Run Change Audio Speed as a Claude MCP workflow

Keep the goal, source assets, and constraints together in the conversation. Ask Claude to restate the source audio and exact speed multiplier before proposing medux_change_audio_speed. That context checkpoint makes the file roles and desired outcome easy to correct before any Medux call is approved.

Claude prompt pattern

Using the assets and requirements in this conversation, help me change audio playback speed with Medux MCP.
Restate which input fulfills each role: the source audio and exact speed multiplier.
Propose the medux_change_audio_speed call and summarize its arguments before asking for approval.
When it finishes, return the speed-adjusted audio with a checklist confirming that the duration and playback speed match the request and the audio remains complete.

Context checkpoint

Have Claude summarize the intended transformation, identify every source asset by role, and list the important constraints. Review that summary together with the proposed tool arguments; correct the conversation first if a file, order, time range, or setting is ambiguous.

Result verification

Keep the Medux task ID in the conversation while Claude checks progress. When processing ends, ask for the speed-adjusted audio plus a concise validation checklist confirming that the duration and playback speed match the request and the audio remains complete.

What this tutorial does

Medux operation

Speed up or slow down an audio file.

Agent workflow

Claude selects medux_change_audio_speed, presents the arguments for review, calls Medux, and reports the response.

Before you start

Authentication

Authentication is required via Authorization header.

Preconditions

Upload the source file and create a file reference before calling this endpoint.
Successful requests return a Medux task record immediately. Use the task query or sync endpoints to track completion.
All file inputs must be uploaded and persisted as file references before submission.

Prompt Claude

Start with a clear instruction that names the Medux operation and the intended inputs.

Speed up or slow down an audio file.

Request fields to review

Confirm these values before approving the MCP tool call. The linked API page remains the source of truth for current limits and response semantics.

Field	Type	Requirement	Purpose
`input_file_id`	string	Required	Input audio file id.
`speed`	number	Required	Positive float, e.g. 1.5 for 1.5x speed.
`model_id`	string	Optional	Model Default: change-audio-speed-default.
`title`	string	Optional	Optional task title.

Step-by-step workflow

Connect Medux MCP to Claude

Add the Medux remote MCP endpoint to Claude, provide an authorized credential, and confirm that the medux_change_audio_speed tool is available.

Prepare the required inputs

Prepare the source files, asset IDs, text, or settings required by the operation. Upload local media first when the tool requests file IDs.

Ask Claude to run Change Audio Speed

Use one direct instruction with the intended values. Claude should select the Medux tool and show the proposed arguments before execution.

Review and approve the tool call

Check that the tool is medux_change_audio_speed and that each file ID, task ID, option, and output setting matches your request before approving it.

Check the Medux response

If Medux returns an asynchronous task, let the agent monitor it until completion; otherwise review the immediate response and save any result identifiers or output URLs.
