Posted on Nov 30, 2016 / Est. budget $ 250 / Project closed
I am in need of a DSP project that will have 1 Single ended Analog audio input and 2 Single ended Analog audio outputs that are 90 degrees apart in phase (hilbert transform) over a audio frequency range of 20Hz to 20kHz. Also an adjustable low-pass, and high pass filter. The hpf and lpf filters can be adjusted by a SPI bus
the circuit should be low latency (real time)

Some possible chip choices:

High Performance Dual Core DSP/MCU Audio Processor

24-Bit, 192 kHz Stereo Audio CODEC

I only need to have a schematic and software designed. If interested, more details will be provided before bidding.
