#### Description #####

SEA lite frequency analysis has a selectable resolution from 128 to 4096 bands, between 0-4 kHz. This tool is great for audio engineers, anyone with a background in linguistics (phonology or phonetics), cognitive psychology (psycholinguistics), speech and music analysis or Digital Signal Processing (DSP). It is a useful tool for off-line frequency analysis of acoustic signals and a powerful 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 high resolution, allowing the user to observe harmonics and the fine structure of their recordings.

Initially it was designed for students and researches in Electronic/Electrical Engineering, however, anyone can try their hand at using it.
It incorporates some past and present state-of-the-art speech enhancement algorithms which allow you to filter out noisy signals and see and hear the result of these algorithms first hand. Some of these algorithms are currently used in some telecommunications systems.

You can quickly make changes and share them with colleagues or teaching staff via e-mail, Blue-tooth and any other supporting image or sound transfer services. All spectrograms and frequency plots are zoom able via an image viewer.

Complete list of features in V2.0.1:
- complete spectrogram analysis
- complete short-time magnitude analysis
- Distort recorded audio with different noise types from -30dB to +30dB
- Additive noise types include:
+ White noise
+ Babble (human voice)
- Exporting of configuration as txt file
- Short-Time Fourier Analysis on all generated audio
- Real time amplitude recording
- dBFS scale on all spectrograms
- Viewing and sharing of all images and audio
- The following Advanced filters:
+ spectral subtraction
+ Frequency Wiener filter
- The following acoustic modification methods:
+ Unit Magnitude
+ Random Phase
+ Zero Phase
- Peak frequency tracking
- Generate spectrogram png files
- Generate .wav files
- comprehensive help and documentation
- Video tutorials

If there is no better APP than this that really would be sad. Dull, some 'Audio Editor' APPs are more exciting. This could be better, doesn't look impressive on my Phone's 1080P Screen, it's B&W fine lines with no zoom.

X70%
by X####:

Records a few seconds then stops. I do not advise this app for anyone.

W70%
by W####:

Don't like it I am uninstalling

J70%
by J####:

This is too restricted to be of an use to anyone, I suspect. Whatever you want with respect to speech/dsp move along this is not the 'droid app you are looking for

It was ok, but please add an adjustable length.

Only handles 3 seconds of audio?

Excellent for something me and my husband found on our voice recorder... found a voice in the back ground telling us "he's a monster" so yeah it definitely works! Thanks so very much!

Better analysis tools on play with better capabilities & UI and miniscule memory use.uninstalled

U70%
by U####:

Im loving the free version so much that i will pay for the full version without a second thought. I like the ease of use and the specto graphs are remarkably detailed, clearly alot of thought went into this app and i can imagine the importance this app would have for a university student studying a related field. Well done all round

Y70%
by Y####:

This app has helped my understanding of dsp based applications, highly Recommended!

Y70%
by Y####:

A handy visualisation tool for introducing students to, or for anyone to explore, the basic concepts of speech enhancement. The drawback is that only a limited range of customisable parameters are available in the free version.

Y70%
by Y####:

I really heard no difference in the enhanced versus the unenhanced. In app file viewer was nearly impossible to load files. Wasted my time.

Y70%
by Y####:

The fact that you can only work with 3 seconds at a time makes this app of great possibility completely useless! Please fix and I'll change my rating
