Delay processor

This program was developed to run on a Huawei HG532s ADSL router. The firmware was modified in order to support ALSA and run this program.

Build prerequisites

To build the program for the router you must save the toolchain under /opt/trendchip/mips-linux-uclibc/ and also save the libraries and includes for alsa-lib (compiled for the router architecture) under /opt/router/alsa-lib/.

Building

To compile the program for the router just run:

PROFILE=router make

If you want to build the program for run it on your PC:

make

Running

Usage:

./build/delay_processor -p <playback_device> -c <capture_device> -t <delay_time in seconds> -f <delay_feedback 0 - 1> -w <delay_dry_wet 0 - 1>

For example, using the plughw:0,0 interfaces, with a delay time of 100 milliseconds (0.1 seconds), 50% of feedback and 50% of dry wet:

./build/delay_processor -p plughw:0,0 -c plughw:0,0 -t 0.1 -f 0.5 -w 0.5
