DFasma ~ Compare Audio Files In Time & Frequency

Posted by tom2tec on

DFasma is free open-source software which is used to compare audio files in time and frequency. The comparison is first visual, using waveforms and spectra. It is also possible to listen to time-frequency segments in order to allow perceptual comparison. It is basically dedicated to analysis. Even though there are basic functionalities to align the signals in time and amplitude, this software does not aim to be an audio editor.

Features:

  • Can load about 25 different audio formats (thanks to libsndfile or libsox).
  • Shows spectrogram, amplitude, phase spectra and group delay.
  • Can play a filtered sound given a selected frequency band.
  • Rectification of the spectrogram tilt (cepstral lifting).
  • Can create and edit segmentation files.
  • Can create and edit fundamental frequency (F0) files (thanks to REAPER).
  • Runs under Linux, Mac OSX and Windows.

foo_wave_seekbar ~ Foobar2000 Waveform Seekbar

Posted by tom2tec on

Enhance the appearance and functionality of Foobar2000 by adding a visual waveform representation of the currently playing audio track, which can be used to navigate to any point in the image of the track by clicking there.

Waveform Seekbar is a UI element for both the Default UI and Columns UI that provides seekbar functionality (seeking, position indicator) on top of a pretty image of the waveform of the currently playing song, drawn using either Direct3D 9.0c or Direct2D 1.0.

Spectro ~ Audio File Analyzer

Posted by tom2tec on

Spectro is a freeware audio file analyzer for Windows. Currently capable of reading FLAC, APE, MP3 and WAV files. Spectro lets you view vital data about compressed audio files and creates a spectrogram of the wave data. This allows you to quickly and easily spot quality issues with a file and also look for transcodes.

ORBAN Loudness Meter ~ Loudness & Peak Display

Posted by tom2tec on

This software simultaneously displays instantaneous peaks, VU, PPM, CBS Technology Center loudness, and ITU BS.1770 loudness. All meters include peak-hold functionality that makes the peak indications of the meters easy to see.

The software accepts two-channel stereo inputs. The VU and PPM meters are split to indicate the left and right channels. The PPM meter also displays the instantaneous peak values of the L and R digital samples. ~ Hydrogen Audio

Foobar2000 ~ Playlist Viewers

Posted by tom2tec on

Foobar2000 Playlist Viewers display the current playlist of songs. Different playlist viewers offer various capabilities such as formatting, grouping and visual options. A playlist viewer is usually the central panel and main focus of a Foobar2000 interface.

  • Navigate to Preferences > Display > Default User Interface > Playlist View > Custom Columns
  • at the bottom of the custom columns windows, click “Add new‘
  • Name the Column “Played‘ and %play_count% as the ‘pattern’
  • click apply, ok
  • Now right click the title bar of the playlist and select “Columns” and make sure ‘Played‘ is selected (checkmarked) and that you can see the column in the playlist, it will be last but you can rearrange it.

Foobar2000 ~ DADA Automatic Song Rating

Posted by tom2tec on

Date and duration adjusted (DADA) auto-rating algorithm for foobar2000

The DADA Auto-Rating algorithm (DAR) automatically rates music according to a variety of statistics collected by foobar2000’s official “playback statistics” plugin.

If done well, an auto-rating algorithm will simply tell you what your favorite (and conversely, least favorite) music is, and the rating will be derived from and reflect actual listening behavior. This is quite different from manual ratings (e.g. 1 – 5 stars set by the user), since there’s very often a disparity between what we’d like ourselves to like, and what we actually like. For those interested in uncovering their actual musical tastes, a good auto-rating formula can be quite illuminating.

MilkDrop ~ Audio Visualization Plugin

Posted by tom2tec on

MilkDrop is a music visualizer – a “plug-in” or extension to Winamp or Foobar2000 music players. As you listen your music in Winamp, MilkDrop takes you flying through the actual sound waves you’re hearing, and uses beat detection to trigger myriad psychedelic effects, creating a rich visual journey through sound. MilkDrop can also be driven by a live audio feed (microphone or line-in).
