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.
Version History Added audio file export choice - choose either Linear PCM (default) or MPEG-4 in the export view. Linear PCM (Pulse Code Modulation) is an uncompressed audio encoding method, representing the raw audio waveform, while MPEG-4 utilizes a compressed format that employs various algorithms to efficiently store and transmit audio data, offering a trade-off between file size and audio quality. 1.0.9 12/15/2023 Maintenance update includes 15 new tone shapes in the sample library (listed at the end of table), the default filename for an exported WAV file is set to the match the document name, improved audio play for previewing very short tone shape audio (0.5 seconds or shorter). 1.0.8 12/08/2023 Maintenance update improves the sound of audio feedback during editing operations. Previous update: 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. 1.0.7 11/28/2023 Maintenance update includes a new tone shape sample #51.

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 novel feature – 'Fidelity.' This option measures the accuracy of the applied curve in matching the actual frequency curve, accounting for the level of time quantization. Higher fidelity values result in a closer approximation to the actual curve, and adjusting this parameter can significantly alter the sound experience. New Samples with Options: Explore the possibilities with four new starter documents in the samples library, each featuring distinct option settings. Dive into a range of sounds and effects to spark creativity in your audio projects. 1.0.5 11/21/2023 Maintenence update puts the new echo volume control into its own section of the options view for clarity; a “Reset All” button has been added to Options; Options are reset when a sample is selected; fixed a misaligned drawing issue with the frequency range selector; other UI improvements. Previous updates: Maintenence update includes a new volume control for the echo effect, set volume from 0 to 1. Specify echo and its volume in the Options view. User interface is no longer adversely affected by the dark mode system appearance. The echo-to-duration ratio is maintained when duration changes; Echo view has new `middle` and `round` convenience buttons to set echo offset value; the selected note frequency, set in the note editor or selection views, has its value removed if its current value is outside any new frequency range; Undo-Redo buttons lost their activation state after viewing the samples or info views. Other improvements. 1.0.4 11/15/2023 Maintenence update includes a new volume control for the echo effect, set volume from 0 to 1. Specify echo and its volume in the Options view.

Other improvements. 1.0.2 11/13/2023 Maintenance update that includes a new option called Wave Type. Use Wave Type to change the audio sampling function from the following waveform types: Sine, Square, Triangle, Sawtooth and truncated Fourier series versions Square Fourier, Triangle Fourier, Sawtooth Fourier. Each type produces a distinct sound. This new option is in the Options view along with the other options Amplitude Scale Type and Echo Offset, that also produce distinct sound. 1.0.1 11/08/2023 1.0 10/31/2023
