Streamed audio must meet the following requirements for use in IDOL Speech Server:
A sampling rate of 8,000 or 16,000 Hz. Audio originally sampled at other rates must be downsampled to either 8,000 or 16,000 Hz. For best results, Micro Focus recommends that you use the highest possible sampling rate.
For example, downsample 44 kHz audio to 16 kHz; downsample 11 kHz audio to 8 kHz. Do not upsample the data, because upsampling often leads to poor results.
There are several third-party tools that you can use to convert audio into the required format.
