Aglaophone Description

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 displaybits -- increase the amount of quantization (decrease the number of bits) of a signal.rawread -- read unformatted sample datarawwrite -- read unformatted sample datamp3gate -- gateway to an MP3 compressor/decompressorsplitter -- generate two outputs from one inputsyncswitch -- switches between two inputs. Supports 'blind test' mode.upsamplefilter -- upsample and then filter a signalfilterdownsample -- filter and then downsample a signaladder -- add two signals together Requirements: · 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.
