## What is ToneShaper?

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.

## Key features

- Graphical frequency plotting
- Add and drag points to shape tones
- Adjust frequency range
- Set cycle duration
- Export audio to WAV
- Library of sample tone shapes

### 5/5 — Is Super Awesome, but one problem

*2025-02-05*

The only problem I have it that I can’t use on my iPhone 16 Pro Max (the latest iPhone model) with the current software IOS version. It only opens to a blank page. The main reason I gave 5 stars is because this app works on my old iPhone 12 Pro Max, and has become essential to me. I love this app, it’s one of a kind for IOS. Especially since Web browser site SheetsofSound is no more. Please fix it to work for iPhone 16 Pro Max.

### 5/5 — Very good and practical

## Frequently asked questions about ToneShaper

### What is ToneShaper?

ToneShaper is a free music application that allows users to create audio tones by graphically plotting frequency over time. You can define tone shapes by adding and manipulating points on a plot and then export the resulting audio as a WAV file.

### How do I create a tone in ToneShaper?

You can create tones by tapping on the plot view to add points with specific frequency and time coordinates, or by drawing shapes in the draw tab and applying them to the plot. You can also start with sample tone shapes from the library.

### Can I export my creations from ToneShaper?

Yes, ToneShaper allows you to export your created audio tones to a WAV file. You can choose the number of cycles for the exported audio, and the total duration is limited by the maximum duration setting.

## Version history (last 5 releases)

### 1.0.9 — 2023-12-15

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.

### 1.0.8 — 2023-12-08

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).

### 1.0.7 — 2023-11-28

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.

### 1.0.6 — 2023-11-23

Maintenance update includes a new tone shape sample #51.

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.

### 1.0.5 — 2023-11-21

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 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.
