SpeakEasy
Introduction
SpeakEasies were nightclubs during prohibition (the 20's), infamous for music, booze, and reefer. Unfortunately, this speakEasy is just a computer program to record, and play back sounds. The top panel is the spectrogram, the bottom panel shows the wave form. These panels are interesting to watch when the sound is being recorded, since the displays are dynamic, ie. continuously updated. Apart from the standard features, it also features an echo effect, which can be toggled on and off. The echo effect is accomplished by use of the EchoFilter class and is set at 1/10 of second, to give the effect of being in an empty room. Sound manipulations are handled by the methods of the Sound class. The sound being displayed above is "beetbatbootbird.wav", which consists of "beet", "bat", "boot", and "bird". Note in waveform, at the end of each of the first three words there is a short silence and then a spike at the end. That is the "t" sound being uttered. Note, that for the last word, the spike is different. This is because a "d" sound rather that the "t" sound is being uttered. The image below is "123.wav" which consists of 1, 2, 3 spoken in English, Chinese and German. In the second image there is a blue horizontal strip going across the spectogram (the first panel). That strip is due to noise from my linux box (which has several fans).
