#### Description #####

SEA lite frequency analysis has a selectable resolution from128to 4096 bands, between 0-4 kHz. This tool is great foraudioengineers, anyone with a background in linguistics (phonologyorphonetics), cognitive psychology (psycholinguistics), speechandmusic analysis or Digital Signal Processing (DSP). It is ausefultool for off-line frequency analysis of acoustic signals andapowerful educational aid for students in those fields ofstudy.

You can record, distort, enhance and modify your ownvoice,giving you the ability to hear and see each step youtake.

One of the frequency analysis tools available is the
spectrogram. The spectrograms generated in SEA are veryhighresolution, allowing the user to observe harmonics and thefinestructure of their recordings.

Initially it was designed for students and researchesinElectronic/Electrical Engineering, however, anyone can trytheirhand at using it.
It incorporates some past and present state-of-the-artspeechenhancement algorithms which allow you to filter out noisysignalsand see and hear the result of these algorithms first hand.Some ofthese algorithms are currently used in sometelecommunicationssystems.

You can quickly make changes and share them with colleaguesorteaching staff via e-mail, Blue-tooth and any othersupportingimage or sound transfer services. All spectrograms andfrequencyplots are zoom able via an image viewer.
