Description

Hello Hackaday makers, I would like to ask for advice about an idea I’m developing. I’m thinking about creating a low-cost audio processing system for music lovers. The device would have two audio inputs and four outputs, and a desktop application would allow users to configure the device and apply audio processing such as: Equalizers to correct the sound for the four outputs Limiters to protect amplifiers and speakers High-pass / low-pass filters (Butterworth, Bessel, etc.) for crossover applications Routing options: L / R / L + R I am planning to add a USB interface for communication with a computer. For audio connections, I’m considering using screw terminal blocks with balanced audio connections. On the front panel, I would like to include: VU meters for the inputs Four push buttons for quick mute control LEDs for clip / mute / signal status One challenge I’m currently facing is implementing delay due to the DSP limitations. The hardware I
