App: ToneShaper
Developer: Limit Point Software
Genres: Music, Education

Create cycles with tone shapes of smoothly varying frequency by plotting frequency at specific times.

Tap the library button to pick from a selection of sample tone shapes to get started.

Tap in the plot view to add points with coordinates (frequency, time). Drag to move points, but limited by the neighbors time.

Alternatively, drag in the draw tab to add points, then apply them to set the points in the plot view.

Adjust the frequency range slider to limit the bandwidth.

Adjust the duration slider to specify the cycle period.

Finally, in the export view you can save the audio to a WAV file with a chosen number of cycles. The duration of the audio is limited by the maximum duration, which therefore also limits the number of cycles in the audio file.

Release notes:
Maintenance update improves the sound of audio feedback during editing operations.

Options in Documents:

All parameters influencing the tone shape's sound, including amplitude scaling, echo offset, echo volume, wave type, and fidelity, are now saved within the document. This ensures that the same sound, along with any unique effects from optional values, can be precisely restored when the document is reopened.

Fidelity:

Introducing a feature – 'Fidelity.' This option affects the time of the frequency changes from the actual curve by altering a scaling factor. Higher fidelity values result in a closer approximation to the actual curve, and adjusting this parameter can significantly alter the sound.

New Samples with Options:

Four new samples that leverage different option values.
