Our broadcasting products capture audio and upload it to the cloud in a lossless .wav format. We then deliver it to listeners in the highest possible quality their phone / current service will allow.
Most live broadcasting apps use VoiP technology, which delivers sounds in ~16 khz. However, because of our process of uploading the original file lossless to the cloud, we're able to deliver the sound in ~48 khz.
Note: After a broadcast ends, the broadcaster can always download the file as a lossless .wav.
