Digital filter solution for music playing

We are looking for a Digital filter solution for music playing, we are not sure whether your company has the suitable chipset or solution for us. It needs to meet the requirements as below:

  1. It can filter the input music data frequency, and divide it to High frequency band, Middle frequency band and Low frequency band.
  2. According to the intensity of the High, Middle and Low frequency band, it outputs the signals of live audio characters for three bands.
  3. The Bandwidths of the High, Middle and low frequency can be dynamically changed according to the different tone of music. It could be a kind of AI adaptive algorithm.

If you have any approximate solution or chipset, please kindly recommend us.

Look forward to your quick reply!

    FPGAs allow you to create whatever functionality you require. Maybe you are asking which device/device family to choose for this task.

        Hi,
        FPGA can do any kind of DSP including audio, but it's not necessarily first choice. I'd rather look for dedicated signal processors, e.g. from Analog Devices or TI. They provide libraries and example code for audio DSP. To design your final application, special engineering skills are required for signal processor as well as for FPGA solution, question is if you have it available. FPGA is more complicated because code needs to be most likely written from the scratch.
        Regards
