Partiels ~ Audio Analysis Application

Posted by tom2tec on

Partiels is an audio analysis application that allows you to explore the content and characteristics of sounds.

Features:

Partiels allows analysis of one or several audio files using Vamp plug-ins loading data files, visualizing, editing, organizing, and exporting the results as images or text files that can be used in other applications such as Max, Pure Data, Open Music, etc.

  • Windows, Mac & Linux support
  • Multiformat support
  • Multichannel support
  • Multiaudiofile support
  • Analyzing audio with Vamp plug-ins
  • Visualizing results as spectrogram, lines, and markers
  • Textual and graphical editing of results 
  • Organizing and ordering analyses in groups
  • Exporting results to PNG, JPEG, CSV, LAB, JSON, CUE, REAPER & SDIF formats
  • Loading results from CSV, LAB, JSON, CUE & SDIF formats
  • Batch processing
  • Command line interface to analyze, export, and convert results
  • Consolidating documents for sharing

Alongside Partiels, a wide range of analyses based on audio engines developed at IRCAM and outside are ported to Vamp plug-ins. These plug-ins allow you to perform FFT, LPC, transient, fundamental, formant, tempo, TTS and many other analyses. You can also find a large number of analysis plug-ins on the Vamp plug-ins website.

audioMotion ~ Player & Realtime Spectrum Analyzer

Posted by tom2tec on

audioMotion is a media player and high-resolution real-time audio spectrum analyzer that allows you to SEE your music! ♪♫🤩

It is completely free, open-source software, created out of my passion for the graphic spectrum analyzers of hi-fi systems from the 1980s.

Features:

Dual channel high-resolution real-time audio spectrum analyzer

  • Media player with subtitles support for audio and video files
  • Fullscreen and Picture-In-Picture display at 60fps, ready for Retina / HiDPI screens
  • Logarithmic, linear and perceptual (Bark and Mel) frequency scales, with customizable range
  • Visualization of discrete FFT frequencies or up to 240 frequency bands (supports ANSI and equal-tempered octave bands)
  • Decibel and linear amplitude scales, with customizable sensitivity
  • Optional A, B, C, D and ITU-R 468 weighting filters
  • Optional effects: vintage LEDs, variable opacity, mirroring and reflection, radial spectrum
  • 17 beautiful color gradients, plus a visual editor to easily create your own gradients
  • Support for M3U playlists (.m3u and .m3u8 file extensions)
  • Visualize audio from your microphone (or “stereo mix”, if your soundcard supports it)

Audio DiffMaker ~ Signal Difference Extraction Software

Posted by tom2tec on

Audio DiffMaker is a freeware tool set intended to help determine the absolute difference between two audio recordings, while neglecting differences due to level difference, time synchronization, or simple linear frequency responses.

The difference recording  that results is only what has changed between the two recordings.  If anything – a change of component, a treatment, mechanical damping, etc. – is having any audible effect on the audio signal in a system, the difference recording will have audible content. The end result is primarily intended to be evaluated by ear.
