![]() Citation from Wikipedia: “A head-related transfer function (HRTF) True 3D sound spatialisation using headphones. The sound effect is achieved using a technology called Head Related Transfer Function (HRTF), which introduces Information about the waveform file to play, the angle position of the board, etc). Optionally, a serialĬonnection (USART with TX=pin PA2, 115200 baud, 8N1) can be used to monitor the application (error messages, Only a mono sound file with sample rate of 44100 Hz will beĪccepted by the application, and headphones should be used to get the best result. Is pressed, which plays the next waveform file. The application plays a waveform file from the root directory of a USB stick in a loop until the blue button The rotation of the horizontal angle (azimuth) is limited from -90° (left) to 90° (right), and vertical angle (elevation) The board can be rotated to the left, right, up and bottom, which will change the direction of the sound source. The 3D sound effect is controlled by the spatial alignment of the board, which uses the MEMS motion sensor to determine its Real-time to produce a three-dimensional sound effect, then sends the output to stereo headphones. ![]() It reads a mono sound waveform file from a USB stick, and processes the sound samples in STM32F4-3DSound is an application that runs on a STM32F4-Discovery board for playing a waveform file withģD sound effects. ![]() View the Project on GitHub cahya-wirawan/stm32f4-3dsound ![]()
