yes undertsood. I tried with the StereoDelay and it works super ! I guess this is not an option for the stereoPlateReverb..? well I tried and it gave an error. No matter. I will also try with the SC reverb but am sure it will work. Originally I...

This method applies only to a few components from my library. It's not a generic way to use PSRAM within the Teensy audio lib.

Some of the RAM hungry effects have an option to start with their sample buffers placed in PSRAM. Using Stereo Delay as an example #include <Audio.h> #include <hexefx_audiolib_i16.h> #include <Wire.h> #include <SPI.h> #include <SD.h> #include...

For longer delays it's worth to add a PSRAM and move the buffers there. Since the delay and reverb objects allocate memory in runtime the RAM2 report does not include them. AudioMemoryUsageMax(); will tell the peak memory usage in blocks. Hope it...

er..ok I answered my own question. I realised that I was allocating too many blocks in AudioMemory() which was eating into RAM2. When I reduce i get: FLASH: code:125376, data:21580, headers:8688 free for files:7970820 RAM1...

TEA 1 0505 won’t be able to power Teensy4.1 + ESP32. 200mA max output current is not enough.

The online LVGL image converter adds more attributes to large constant arrays: #ifndef LV_ATTRIBUTE_IMAGE_IMG_NAME #define LV_ATTRIBUTE_IMAGE_IMG_NAME #endif const LV_ATTRIBUTE_MEM_ALIGN LV_ATTRIBUTE_LARGE_CONST LV_ATTRIBUTE_IMAGE_IMG_NAME...

Is this where you brag about your projects? Here's an audio equalizer and general purpose DSP platform I put together. It's made up of an Teensy 4.1 for the DSP, a CYD (Cheap Yellow Display) for the visual part of the UI and a ES9039Q2M board I...
