.. and add a very basic audioeffects test, showing that it plausibly is working I had to address several build errors that occurred in the Unix build, mostly related to conversion from FP types to integral types (replaced by explicit casts) and by accidental mixing of regular & f-suffixed floating constants (replaced with the MICROPY_FLOAT_CONST macro) Particularly this change could use consideration: ```diff - self->max_echo_buffer_len = self->sample_rate / 1000.0f * max_delay_ms * (self->channel_count * sizeof(uint16_t)); // bytes + self->max_echo_buffer_len = (uint32_t)(self->sample_rate / 1000.0f * max_delay_ms) * (self->channel_count * sizeof(uint16_t)); // bytes ``` The buffer length is being calculated in floating point based on the millisecond delay & the sample rate. The result could then be a fractional number such as 529.2 for a 12ms delay at 44.1kHz. Multiplying a floating number by the size required for each echo buffer item (`(self->channel_count * sizeof(uint16_t))`) could yield a number of bytes that doesn't correspond to an integral number of buffer items. I grouped the float->int conversion so that it converts the number of echo buffer items to an integer and then multiplies by the size of the item. |
