EasyQ ~ Easy To Use Equalizer


EasyQ is an easy-to-use equalizer with an arbitrary number of filter stages in series connection. Each of the filter stages can operate in one of the following modes: peak/cut (aka bell or parametric EQ), high- or low-shelving, notch and low- or highpass (both with either 6 or 12 dB/oct slope). EasyQ is also easy on the CPU and just does what an EQ is supposed to do without performing any additional voodoo. As such, it is well suited to serve as a go-to EQ for the routine equalizing tasks.

Key Features:

  • unlimited number of filter stages (“bands”)
  • each stage can be one of the following characteristics: bell, low-/high-shelf, low-/highpass (6 or 12 dB/oct), notch
  • clean equalization – no additional colorations
  • low CPU usage
  • +-48 dB gain range
  • stereo modes: linked, left/right, mid/side and mono
  • minimum phase response

Cdrdao ~ Disk-At-Once Recording


Cdrdao records audio or data CD-Rs in disk-at-once (DAO) mode based on a textual description of the CD contents.

Advantages of Disk-At-Once (DAO) Recording:

Recording in disk-at-once mode writes the complete disc, i.e. lead-in, one or more tracks and lead-out, in a single step. The commonly used track-at-once (TAO) mode writes each track independently which requires link blocks between two tracks. Older CD-recorder models forced a two second pause (pre-gap) between two tracks whereas newer models allow adjusting of the pause length in TAO mode reducing the number of link blocks to a minimal amount. However, with TAO it is generally not possible to define the data that is written in pre-gaps. But exactly this feature makes audio CD recording interesting, e.g. by creating hidden bonus tracks or track intros in pre-gaps like it is common habit on commercial CDs. Finally, DAO recording is the only way to write data to the unused R-W sub-channels for e.g.  CD-G or CD-TEXT.

Features:

  • Full control over length and contents of pre-gaps (pause areas between tracks). Pre-gaps may be completely omitted, e.g. for dividing live recordings into tracks.
  • Control over sub-channel data like:
    • catalog number
    • copy, pre-emphasis, 2-/4-channel flags
    • ISRC code
    • index marks
  • Support for exact audio, data and mixed mode CD copying.
  • Support for R-W sub-channel writing.
  • Tracks may be composed of different audio files supporting non destructive cut.
  • Accepts WAVE and raw audio files.
  • CD-TEXT reading and writing with drives that support it.
  • CDDB access to automatically create CD-TEXT data.
  • Support for on-the-fly copying.

SpatGRIS ~ Multichannel Composition


The SpatGRIS is a plugin (Mac AU/VST and VST Windows format) designed to compose multichannel space. It allows the user to spatialize the sound in 2D (up to 16 speakers) or in 3D (up to 128 speakers) under a dome of speakers (with the ServerGRIS, available also on SourceForge). It includes two audio modes, — Free Volume and PanSpan — and one OSC mode. SpatGRIS is a fusion of two former plugins by the GRIS: OctoGRIS and ZirkOSC with a lot of new features. Automated Trajectories are included. It is possible to control it from external controllers such as Joystick, iPad or Leap Motion.

Features:

  • Three modes: Free Volume, Pan Span, OSC Spatialization
  • Automated Trajectories
  • Up to 16 outputs in audio mode
  • OSC Mode to control the ServerGRIS
  • External controllers: Joystick, iPad. Leap Motion

BPM Counter ~ Beats Per Minute mp3 Tagger


BPM Counter is a fast and accurate beats per minute detector for MP3 music. It may be helpful for DJs who need to get information about the entire music collection quickly and for any kind of remixing/sampling stuff. Do not trust online BPM databases, because each musical composition can have several versions with a different tempo. Don’t waste your time for manual tapping with a metronome, just navigate to any folder with music and BPM finder will show all compatible audio files (MP3 and WAV) and start BPM detection automatically.

Have you already encountered the fact that your analyzer returns half or double value? This is a fairly common mistake, called an octave error. Most often this happens with simplified algorithms that cut off the frequency spectrum of the audio signal. Seeing that, we use full-range audio decoders from Audio Converter Plus to ensure a balance between performance and precision.
