ElevenLabs Invalid Audio Sample Rate

Understanding ElevenLabs Voice AI API

ElevenLabs is a leading provider of Voice AI APIs, designed to transform text into natural-sounding speech. These APIs are widely used in applications ranging from virtual assistants to accessibility tools, enabling developers to integrate advanced voice synthesis capabilities into their products.

Identifying the Symptom: Invalid Audio Sample Rate

When using the ElevenLabs Voice AI API, you might encounter an error message indicating an 'Invalid Audio Sample Rate'. This error typically occurs when the audio file you are working with has a sample rate that is not supported by the API.

Common Error Message

The error message might look something like this: Error: Invalid Audio Sample Rate. Supported sample rates are 16000 Hz, 22050 Hz, and 44100 Hz.

Exploring the Issue: Why Sample Rate Matters

The sample rate of an audio file determines the quality and size of the audio data. The ElevenLabs API requires audio files to be in specific sample rates to ensure compatibility and optimal performance. Using an unsupported sample rate can lead to errors and prevent the API from processing the audio correctly.

Supported Sample Rates

The ElevenLabs API supports the following sample rates: 16000 Hz, 22050 Hz, and 44100 Hz. Any deviation from these rates will result in the 'Invalid Audio Sample Rate' error.

Steps to Resolve the Invalid Audio Sample Rate Issue

To fix this issue, you need to convert your audio file to one of the supported sample rates. Here are the steps you can follow:

Step 1: Check the Current Sample Rate

First, determine the current sample rate of your audio file. You can use tools like FFmpeg to check the sample rate. Run the following command in your terminal:

ffmpeg -i your-audio-file.wav

Look for the 'Hz' value in the output to identify the current sample rate.

Step 2: Convert the Audio File

Once you know the current sample rate, use FFmpeg to convert the audio file to a supported sample rate. For example, to convert to 44100 Hz, use the following command:

ffmpeg -i your-audio-file.wav -ar 44100 output-audio-file.wav

This command will create a new audio file with the desired sample rate.

Step 3: Verify the Conversion

After conversion, verify that the new audio file has the correct sample rate by running the FFmpeg command from Step 1 again on the output file.

Conclusion

By following these steps, you can resolve the 'Invalid Audio Sample Rate' error and ensure that your audio files are compatible with the ElevenLabs Voice AI API. For more detailed information, you can refer to the ElevenLabs Documentation.
