CUE/WAV Extract Utility


This is an utility for batch extraction of individual tracks from .CUE/.WAV audio disk images, which for instance, are created by Exact Audio Copy software.

While PC users still have other methods of playing tracks from CUE files (by e.g. using Foobar2000, or mounting the image via Daemon Tools), Mac OS X users’ choice is limited, so therefore this utility was written.

The utility is built using Trolltech/Nokia Qt, and those, who would like to rebuild it from the source code – will require this library.

This software is in a public domain and thus can be used or modified for any purpose.

RTL Utility ~ Measure Round Trip Latency


RTL Utility is a tool for measuring the Round Trip Latency of your Digital Audio Workstation (DAW) and audio interface. The utility is used for low latency performance testing by system builders, reviewers, device manufacturers and at dawbench.com.

When your DAW sends data to your audio interface for playback, it doesn’t send a continuous stream of data one bit at a time. What it does is fill up a section of RAM called a buffer and sends that in a single message when it is ready. Before sending the next message it has to fill the buffer again. This wait time introduces a latency, or delay, between something happening in your DAW and when you actually hear it.

While you are recording, the audio interface buffers and sends data to your DAW in a similar fashion. This introduces latency into your recordings.

If you send a signal from your DAW, out through the audio interface and back in via a loopback patch, then there will be a round trip latency which is the sum of the output and input delays. This is the RTL.

Deej ~ Hardware Volume Mixer


deej is an open-source hardware volume mixer for Windows and Linux PCs. It lets you use real-life sliders (like a DJ!) to seamlessly control the volumes of different apps (such as your music player, the game you’re playing and your voice chat session) without having to stop what you’re doing.

J-Scope ~ Oscilloscope VST Plugin


J-Scope is a VST oscilloscope plugin, which can prove invaluable to anyone who develops audio software and has a need to diagnose problems or visualise waveforms.

In operation it is very similar to a real oscilloscope, and most controls will be familiar to anybody who has used a hardware ‘scope. The addition of a control for phosphor decay time allows the examination of rapidly changing waveforms as well as slowly evolving sound envelopes.

J-Scope accepts a stereo signal, and can display it in several modes:

  • Two separate traces, L and R
  • Single trace, sum of L and R
  • Single trace, difference between L and R
  • X/Y (Lissajous) plot, L vs R
  • X/Y (Lissajous) plot, Sum(L+R) vs Diff(L-R)

Satunes ~ Android mp3 Player


Satunes is an mp3 player on Android. Use it to listen your music from your audio files stored in your Android phone (Android Lollipop 5.1.1 and later).

Able Player ~ Web Server Side Player


Fully accessible cross-browser HTML5 media player.

Features:

  • Supports both audio and video.
  • Supports either a single audio track or an entire playlist.
  • Includes a full set of player controls that are keyboard-accessible, properly labeled for screen reader users, and controllable by speech recognition users.
  • Includes customizable keyboard shortcuts that enable the player to be operated from anywhere on the web page (unless there are multiple instances of the player on a given page; then the player must have focus for keyboard shortcuts to work).
  • Features high contrast, scalable controls that remain visible in Windows High Contrast mode, plus an easy-to-see focus indicator so keyboard users can easily tell which control currently has focus.
  • Supports closed captions and subtitles in Web Video Timed Text (WebVTT) format, the standard format recommended by the HTML5 specification.
  • Supports chapters, also using WebVTT. Chapters are specific landing points in the video, allowing video content to have structure and be more easily navigated.
  • Supports text-based audio description, also using WebVTT. At designated times, the description text is read aloud by browsers, or by screen readers for browsers that don’t support the Web Speech API. Users can optionally set their player to pause when audio description starts in order to avoid conflicts between the description and program audio.
  • Supports audio description as a separate video. When two videos are available (one with description and one without), both can be delivered together using the same player and users can toggle between the versions.
  • Supports adjustable playback rate. Users who need to slow down the video in order to better process and understand its content can do so; and users who need to speed up the video in order to maintain better focus can do so.
  • Includes an interactive transcript feature, built from the WebVTT chapter, caption and description files as the page is loaded. Users can click anywhere in the transcript to start playing the video (or audio) at that point. Keyboard users can also choose to keyboard-enable the transcript, so they can tab through its content one caption at a time and press enter to play the media at the desired point.
  • Features automatic text highlighting within the transcript as the media plays. This feature is enabled by default but can be turned off if users find it distracting.
  • Supports YouTube and Vimeo videos.
  • Provides users with the ability to customize the display of captions and subtitles. Users can control the font style, size, and color of caption text; plus background color and transparency; all from the Preferences dialog. They can also choose to position captions below the video instead of the default position (an semi-transparent overlay).
  • Supports fallback content if the media cannot be played (see section on Fallback for details).
  • Includes extensive customization options. Many of the features described above are controlled by user preferences. This is based on the belief that every user has different needs and there are no one-size-fits-all solutions. This is the heart of universal design.
