audio_tools::MozziStream Class Reference

We use the output functionality of Mozzi to output audio data. We expect the data as array of int16_t with one or two channels. Though we support the setting of a sample rate, we recommend to use the default sample rate from Mozzi which is available with the AUDIO_RATE define. More...

Detailed Description

We use the output functionality of Mozzi to output audio data. We expect the data as array of int16_t with one or two channels. Though we support the setting of a sample rate, we recommend to use the default sample rate from Mozzi which is available with the AUDIO_RATE define.
