Abstract

For live digital audio systems with high-resolution multichannel functionalities, it is desirable to have accurate latency control and estimation over all the stages of digital audio processing chain. The evaluation system we designed supports 12 channel, 24 bits Sigma Delta based ADC/DAC, incorporating both a programmable FPGA and a Digital Signal Processor. It can be used for testing and evaluation of different ADC/DAC digital filter architectures, audio sample buffer subsystem design, interrupt and scheduling, high level audio processing algorithm and other system factors, which might cause the latency effects. It also can estimate the synchronization and delay of multiple channels.
