Standard Audio File Handling
You can open existing audio files as well as record a new one from
scratch. When browsing for a file to open, you can preview the selected
file by simple button click.
Voice Signal Spectral Analisys
Spectral analysis is the short-range Fourier transform calculated
on each frame of the voice signal.
Though the time-based voice signal representation in time and amplitude
coordinates contains all the information on signal (that is, volume,
pitch, tone), such representaion allows defining and modifying amplitude
of the signal only. Spectral characteristics of a particular sound
gives much more information on its frequency components.
If you edit not the whole voice file but individual fragments,
you may find that sometimes playback produces audible clicks and
pops on edges of the edited fragment. This is because of lack of
concert between the fragment and the unchanged part of the signal.
Frame matching lets you correlate the original and processed sound
shapes by simple spline ajustment!
Voice Signal Analysis of Spectral
Spectral analysis is the short-range Fourier transform calculated on each frame of the voice signal.
AlienTune allows viewing and rotating three dimensional (3D)
specrum graph built in coordinates of time, frequency and amplitude.
The Harmonics view displays the voice component as the harmonics
Voice component forms the base of vocalised sounds (vowels and
voiced consonants). It forms the harmonic structure in the spectrogram
and may be seen as the maximums on divisible frequensies.
Individual Harmonics Editing
There is no audio editors available on the market that supports
this unique feature! You can select individual harmonics and change
its amplitude easily!
High precision parametric analisys
Parametric analisys unveils the next step in voice signal editing. It allows to recreate the signal given modifications of the following three factors: amplitude, pitch and time.
Convenient Graphical Spectral and Parameter Views
The Spectrogram, Harmonics and Noise views of the spectrogram window serve to demonstrate the analysis result and edit in spectrum area, select the fragment and then switch to frame-based voice and noise spectrum envelope editing mode and spectrum morphing. The Harmonics and Noise views represent the voice and noise components as the harmonics path and spectrum path, respectively. The Spectrogram tab displays the resulting signal spectrum that is the result of the parameterized synthesis. Amplitude, Frequency and Time Factor views display the corresponding factor values.
Independent parameters editing
This feature allows to vary the speech intonation and tempo as well as correct the pronunciation. Editing the amplitude affects overall change in the voice and noise spectrum envelope amplitude. Editing the time spline impacts the length of the corresponding frames. Editing the time spline affects base pitch change.
Spectral morphihg is a smooth voice signal parameters reforming from one frame to another through the series of the intermediate frames according to the user-defined path. The use of morphing allows building the temporary phoneme by defining the starting and ending phoneme spectrum. Besides, it is possible to realize the smooth phoneme conjunction by using the spectrums of the two phonemes.
Synthesis and Playback the Signal
AlienTune allows you not only to modify parameters of the voice signal, but build the resulting temporary signal according to the modified parameters and play it on the fly! Play with sound as you like!
