Apologies for incompatibilities on devices other than the oneslisted above. If you find any bugs or issues please e-mail me(miscanalysis@gmail.com) andinclude what you were doing at the time the bug occurred so I canfix it. If it happens I can't support your device I WILL REFUNDYOUR MONEY.
#### Description #####
SEA frequency analysis has a selectable resolution from 128 to4096 bands, between 0-4 kHz. This tool is great for audioengineers, anyone with a background in linguistics (phonology orphonetics), cognitive psychology (psycholinguistics), speech andmusic analysis or Digital Signal Processing (DSP). It is a usefultool for off-line frequency analysis of acoustic signals and apowerful educational aid for students in those fields of study.
You can record, distort, enhance and modify your own voice,giving you the ability to hear and see each step you take.
One of the frequency analysis tools available is the
spectrogram. The spectrograms generated in SEA are very highresolution, allowing the user to observe harmonics and the finestructure of their recordings.
Initially it was designed for students and researches inElectronic/Electrical Engineering, however, anyone can try theirhand at using it.
It incorporates some past and present state-of-the-art speechenhancement algorithms which allow you to filter out noisy signalsand see and hear the result of these algorithms first hand. Some ofthese algorithms are currently used in some telecommunicationssystems.
You can quickly make changes and share them with colleagues orteaching staff via e-mail, Blue-tooth and any other supportingimage or sound transfer services. All spectrograms and frequencyplots are zoom able via an image viewer.
