The essential tool for digital voice processing.

SoundLandscape is a 3D spectral parametric voice signal and sound editor. Designed for professionals working with voice, SoundLandscape offers advanced voice editing capabilities, for example, signal spectral editing. Its flexible workflow, coupled with exceptional ease of use and precise editing tools, gives you the power to process digitized voice data in every possible aspect.

Unlike other digital audio editors available on the market, SoundLandscape is a highly specialized product. It was designed to process voice audio files containing recorded human speech. Such specialization allows to implement a range of digital sound processing features and tools applicable to human speech.

Whether you need to record and/or modify a human voice file, SoundLandscape has you covered with a complete set of tools.

Voice signal spectral analysis: 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. SoundLandscape allows viewing and rotating three dimensional (3D) specrum graph built in coordinates of time, frequency and amplitude.
High precision parametric analysis: 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 morphing: Spectral morphing 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 of the signal: SoundLandscape 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!
