Adjust the Quality & Size of Audio Clips

Easily change the bitrate & sample rate of any audio clip.

Webhooks & Cache Audio Files

Once you have initiated an encoding process any future call with the same parameters will return the current status of the encoding job. So if you run the same conversion multiple times, you will receive its current status immediately.

 

Once the audio transcoding has completed, a webhook will be sent, notifying your application.
