Aglaophone is a system of interconnectable modules for the recording, processing, and playback of real-time audio
Aglaophone is a system of interconnectable modules for the recording, processing, and playback of real-time audio. It features a real-time spectrogram display for visualization along with a number of processing modules. Modules include filters, downsamplers, upsamplers, and quantizers. An MP3 comparison module allows interactive blind comparison of MP3 encoded audio with CD audio, demonstrations of spectral imaging, quantization, and Smith-Barnwell filter bank based wavelet decomposition are included, and there is a module that can perform an automatic spectral analysis of a speaker system.
Modules with the following functionality are included in the application:
soundcardio -- recording/playback with an off-the-shelf soundcard. Supports oversampling and oversampling anti-alias/anti-image filtering.
spectr -- real time spectrogram and oscilloscope display
bits -- increase the amount of quantization (decrease the number of bits) of a signal.
rawread -- read unformatted sample data
rawwrite -- read unformatted sample data
mp3gate -- gateway to an MP3 compressor/decompressor
splitter -- generate two outputs from one input
syncswitch -- switches between two inputs. Supports 'blind test' mode.
upsamplefilter -- upsample and then filter a signal
filterdownsample -- filter and then downsample a signal
adder -- add two signals together
500 MHz Pentium or equivalent (Alpha, Sparc, and PowerPC should work, but have not been tested)
Kernel 2.0 or better
ALSA sound drivers http://www.alsa-project.org v0.9.x
A java compiler and Java 2 runtime are required, but included in the "complete" download.
an mp3 encoder -- required for real-time mp3 comparison. bladeenc, lame, oggenc and the FhG l3enc are supported.
