Dear All:We have project based on the AMICAM1\UltrasoundFFT project and would like add algorithms in it.There are two major thread in the proect as below.First I use simulation data(different frequency tone) instead of real ADC data to test FFT algor...
Inquiries regarding spiritDSP.We are implementing mp3 with DAC DMA using SpiritDSP.The time to play depends on the samplerate and bitrate of the mp3 file.The original time is 3 minutes and 10 seconds,The playback time is different as shown below.The ...
Posted on February 01, 2018 at 12:55 Hi everyone: I am trying to build an audio effects processor on the STM32F7Discovery board. I am relatively new to this matter as I have never used a microcontroller before, and I am having a bit of trouble tr...
Posted on November 25, 2017 at 17:09Hello everyone,a while ago I started looking into the STM32746 to test some DSP audio effects, but I don't have much experience with STM32 MCUs. I mainly had issues with sdram access (see https://community.st.com/...
Posted on September 09, 2015 at 10:05Hi guys, I am intend to using STM32f4 Discovery as sound board, the problem I am only able to play one audio in one time, I need 3 or 4 audio overlapping. is it possible to mix the audio buffer in firmware ? so ...
Posted on June 17, 2014 at 11:38hi everybody!I want to input two audio signals (electronics completed from mic to stm32f4, 1 analog pin and 1 ground) to the stm32f4. Then I want to mix the two audio signals with one signal at half volume and the oth...
