Release notes for v1.1

New

Estimation delay

The estimation delay finder works in the background and can predict values up to 1.5 seconds at 48kHz.

Recent files

The recent files menu allows you to quickly reopen any of the last sessions.

Auto save

The application automatically saves the current project in the background. When next time you run the app, it will start from the last project.

Reset button

Reset button added to the measurements properties. You can quickly reset average buffers.

Loop

Internal loop buffer added, filled with generator samples. In each measurement, you can select loop buffer as a measurement or reference.

CSV import

Any stored measurement could be exported in CSV format.

Log impulse

Add log scale for y-axis on impulse response.

Peak hold

Displaying peak value added to RTA chart and level meters.

Import impulse

Now you can import impulse response data from CSV or WAV files.

WAV export

Any stored measurement impulse could be exported in WAV format.

SNR

A coherence chart has a new option to show data as SNR.

Source selection

For each chart can be selected specific sources to show or hide.

Ignore coherence

You can ignore coherence on the specific stored data and force it to be 100%.

Graphics

Open GL2

On old computers, where Open GL3.3 is not available, the program will automatically fall back to Open GL2. That returns support of old video adapters on modern operating systems. Such as Intel HD3000 on Windows 10.

Math source

DB and power functions

Math source has now four options: vector, polar, dB and power. For the last three options, phase is calculated as polar type.

Count

Added selection of sources counts: from 2 to 10.

Coherence

The resulting coherence value is calculated as the weighted by module value sources average coherence.

Polar phase

New math for polar type provides more useful results.

Phase subtract

Phase subtract for polar types reworked.

Auto name

If you didn't change the name of the math source, it will be updating automatically with the selected type and function.

Color labels

In the right tab, the source shows helping mini colour labels of selected sources.

Experimental function

Show experimental function

You can choose in the menu if you want to use or hide the experimental functions, that's usually not needed but could be interesting in the labs or education.

Crest factor

The crest factor chart shows the rate between peaks and average values measurements.

Nyquist

Classic Nyquist plot is added.

Phase delay

Added plot of phase delay.

Improvements

LTW

LTW transform prepares with knowledge of the current sample rate. That allows achieving the same frequencies list at different sample rates.

Linear mode

A magnitude chart can show data not only as dB difference but linear too.

FFT powers

Added 11 and 14 powers.

Group delay

The charts renderer reworked. Now it shows smooth series with any PPO settings.

Auto names

A new store has an auto name when created, it includes the name of the source and current time.

Windows audio

Improvements of native Windows audio backend. Now it supports multichannel inputs.

Support small screens

Layout can adapt for a tiny screen on microbooks or tablets

Spectrogram level normalization

Levels now correspond to RTA values.

Enable high dpi scaling

Support screens with high pixel density on all the platforms. Such as a 4K 13 inches monitor.

Polarity button

The polarity reverse button clearly shows the status and took less space.

Saved sources

Add saving and loading at the project file ELC and math source.

Shift key

Use shift key for accuracy adjusting values.

Last used folder

The application will remember the last folder you used to open a project.

Scroll

Added scroll to the tablets side menu.

Updater

When a new update is available, an updater will show you your current version and suggested one.

Fixes

Reset buffers

Fix for bug: sometimes buffers weren't reset.

Generator

Fix for the level ignoring bug when generators works with wav file.

Metal renderer

Fix crash on resize chart.

Import bad files

If an imported file has invalid values, "*" instead of digits, this value won't be ignored and imported as zero.

Load bad files

Fix crash on load disabled measurement.

Audio

Fixes for audio client for Windows 7.

Layout

Fixes lots of layout issues

Other

Lots of major and minor fixes

Notes

Optimization

Added a lot of optimizations for better CPU and GPU loads.
