AssemblyAI is a leading Voice AI API company that provides developers with advanced speech-to-text capabilities. This tool is designed to help engineers integrate voice recognition features into their applications, enabling functionalities such as transcription, sentiment analysis, and more. By leveraging AssemblyAI, developers can build applications that understand and process human speech efficiently.
When using AssemblyAI, you might encounter an error indicating that the 'Audio Duration Limit Exceeded'. This symptom is observed when the audio file you are trying to process surpasses the maximum duration allowed by the API. As a result, the API returns an error, preventing further processing of the audio file.
The 'Audio Duration Limit Exceeded' error occurs because AssemblyAI imposes a limit on the duration of audio files that can be processed in a single request. This limitation ensures optimal performance and resource management. If your audio file exceeds this limit, the API cannot process it, leading to the error.
The root cause of this issue is straightforward: the audio file's duration is longer than the maximum allowed by AssemblyAI. This can happen if you are working with lengthy recordings or if the audio file was not trimmed appropriately before submission.
To resolve the 'Audio Duration Limit Exceeded' error, you can take the following steps:
First, check the AssemblyAI documentation to find the maximum audio duration allowed. You can find this information in the AssemblyAI Documentation.
If your audio file exceeds the duration limit, you need to trim it. You can use audio editing tools like Audacity or command-line tools like ffmpeg
to cut the audio file to the required length. For example, using ffmpeg
:
ffmpeg -i input.mp3 -t 00:29:59 output.mp3
This command trims the audio to 29 minutes and 59 seconds.
If trimming is not feasible, consider splitting the audio into smaller segments that comply with the duration limit. Again, ffmpeg
can be used to segment the audio:
ffmpeg -i input.mp3 -f segment -segment_time 1800 -c copy output%03d.mp3
This command splits the audio into 30-minute segments.
Once the audio is trimmed or segmented, submit each segment individually to AssemblyAI for processing. Ensure that each request complies with the API's duration limits.
By understanding the limitations of AssemblyAI and taking appropriate actions to trim or segment your audio files, you can effectively resolve the 'Audio Duration Limit Exceeded' error. For more detailed guidance, refer to the AssemblyAI Blog for additional resources and tips.
