Postman Collection for Dolby Media Enhance API

Jump start exploring Dolby Media Enhance API using this postman collection to improve your audio files like reducing background noise, improving speech quality and much more. This collection will save you a lot of time of manually setting up each request.

Dynamic Requests

Data & Request URL required for reuqests are dynamically set via collection variables.

Job Result Polling

Once you 'Run' the collection, at 'Check Progress Status' request, it will keep polling every 10 seconds (for a total minimum of 30 seconds) and prints the result so you don't have to manually call the endpoint to check it. NOTE: Sometimes it takes more than 30 seconds for the job to change it's status from Pending to Running. In such cases you will need to update the collection variable 'polling_retries' to 4 (meaning it will poll for 4 times - taking 40 seconds instead of default 3 times taking 30 seconds).
