Audio Signal Resampler amd Player with with Cylcone 4 FPGA

Realtime audio resampler with Cyclone 4
	Cyclone IV 48kHz 96kHz 192kHz 384kHz 768kHz sample rates	Base Hardware Unit Altera Cyclone IV + ADC/DAC board The Altera Cyclone 4 DE2-115 from Terasic is used to implement a high resolution sample rate converter for real time audio play back at any desired sample rate. The material stored in block ram and can be continously sampled at any given audio frequency. Thus it is possible to tune audio material to slightly differing audio streams in real time- FPGA Design The analog audio is upsampled to 768 kHz for highest precision during playback. For special operation even clock resampling can performed with the multi rate clock resampler.
