Whistle a melody and watch this program graph the pitch in real time! The Frequency Analyzer, technically speaking, performs a Fast Fourier Transform of the sound (you do need a sound card and a microphone to use this program). What it means is that it analyzes your voice and splits it into its component frequencies so that you can watch patterns of speech, the harmonics of vowels and the noise of sibilants. You can also learn more about the Frequency Analyzer and download the C++ code that performs the FFT.

Displays frequency evolution in time and measures the range that contains 50% of voice power, it is useful to study voice rhythm and to 'see' voice with time perspective.

Issues brain wave freq. tones in stereo difference, major chords synthesis in evolution to a higher octave, feel 3D relaxing and harmonizing sounds. Also displays color associated with required tone and RGB value in hex.

Counts the number of PHI relations in voice frequency formants and displays a graph with its evolution in time. PHI appears in most nature manifestations, feel and see it in your voice and learn how to control it.

Displays accumulated voice frequencies in a radial format providing a convenient depicture of voice freq. distribution, accumulated freq. distribution 'shape' can provide extensive information about the speaker. See the difference between these shapes depending on your emotional state.

Performs voice analysis generating v2v balancing tones. These tones generate balance improving and harmonizing the quality of your voice. PHI (golden mean) analysis is also provided indicating how harmonic (i.e. beautiful)your voice sounds. Tone generation dialog controls brain compatible wave generation including (Alpha, Beta, Theta, Delta). Voice is displayed in several ways including: Voice line graph; Accumulated frequency line graph; Radial Spectrograph; Main octave bar graph; Accumulated grid of music notes; PHI relations in voice;

Plays sound in octave 0 scale associated with corresponding planet (including Sun & Moon) rotation period, brain wave octave difference -based in main planet tone- can be added. Generated tone can be saved to a wav file at 44100 sample rate. Shows panel with frequency mapping colour. Misc. features: volume control, duration control in secs., planet effect description table and Autoplay on select. More info at Hans web site worth to visit!

Generates a cero phased composed sound based in input recording, say a word and it will generate the list of formants, playing generated tone you will hear the vibration associated to the substance related to this word. Additional effects based in brain wave differences can be added.

Enables visualisation and interaction with Lissajous figures, a scattered composition of two waves, they represent a link between vibration and matter as composed grids are those found in crystalline substances. Includes preset values and a random generator, try the 115,187 preset pair an oscillating pattern of a butterfly wing. Hear the figure with the autoplay feature, plays 3 octave midi chord with the selected M,N values in octave 0 scale

Analyses main voice parameters including Shimmer (volume variations), Jitter (freq. Variations) and N2H (Noise to Harmonic). Exhaustive studies can be found linking measurements and variation of these parameters with emotional and physical states.

Measures voice shape with the 30% of total frequency power generating tones based on its mirror (max-v(i)), these tones are rich in deficit frequencies and sound similar to nature environments, hard to believe until you hear them!. Trace of PHI relations in voice and rhythm is also provided.

Generates stereo tone based in L+R channel algebraic expressions, supports (), +-*/, sin cos exp log log10 sqrt asin acos atan sqrt abs and the PI and PHI constants. Math is a gateway for generating vibrations and feeling them trough sound.

Voice Balancing System analyses your voice and generates a v2v (Voice2Voice) balancing tones, includes: easy open wav file capability, complete wav file parameter display (samples, samp. rate, etc...) , real time recording, analyses up to 25" of voice with circular buffer management, save recording to .WAV file for later use, sound graph with Pan/Zoom capabilities, musical grid containing power proportional hits of musical notes, bar graphs associated to musical grid displaying totals and octave bars, plays note contained on musical grid, info grid with complete set of PHI (0.618…) based relations of formants. Full 5 octave FFT display with local scale and Note grid optional display. Radial spectrograph in note/octave and FFT format, Harmonic wheel with musical notes relations. V2V graph containing formants and mirror values (max-v[i]) Formant grid, v2v Tone control generation panel.

ChordXplorer. Plays main western chords in selectable octave and base tone. Midi check box selects source of sound -midi piano or sine wave-

v2v Balancing Chat enables a V2V (Voice2Voice) dialog, just talk and listen to generated v2v balancing tones, or just keep in silence and listen and it will generate random tone patterns.

Voice Rings. Displays concentric circles coloured with formants frequencies, this can give a visual idea of harmonic relations between them, as a harmonic colour combinations will indicate close to harmonic voice formants. Each one of four circles displays proportional part of formants in normal reading order.

D4Sound analyzes the sound from CD audio or a music file and animates a display to reflect it. You can use the Windows multimedia player or CD player and adjust a range of options. The program features real-time DirectX 3D graphics, light color animation, object movement, and much more. D4Sound supports output to Windows at any DirectX 7.0 resolution the graphic card supports. Users may add 3D objects and backgrounds.

Say hello to AnalogX DCOffset, and say goodbye to DC offset headaches forever! DCOffset is the ONLY DirectX Audio plugin capabable of not only correcting DC offset, but detecting and analyzing DC offset audio in realtime! Forget using a seperate application that has to scan the entire file before it can even get an approximate reading - DCOffset can do better after processing less than 10 seconds of incoming audio. Of course, DCOffset requires an application that supports DirectX Audio plugins (like the Paris or WaveLab), and works with either the realtime or non-realtime applications as well. DCOffset supports mono or stereo sound streams, as well as 16bit and 32bit data types.

Introducing AnalogX SampleSlide, the FIRST and ONLY sample-accurate delay mechanism for DirectX Audio! That's right, sample accuracy; not just milliseconds (although you can use those also), but resolution down to each and every sample of the digital stream. Not only that, each stream can be delayed up to 2 seconds (it's limit, assuming 44.1k audio) and STILL maintain absolute sample accuracy. Of course, SampleSlide requires an application that supports DirectX Audio plugins (like the Paris or WaveLab), and works with either the realtime or non-realtime applications as well. SampleSlide supports mono or stereo sound streams, as well as 16bit and 32bit data types.

Have you ever wanted to get a tap delay sounding just right, and fiddled for hours with millisecond delay, trying to get it tight? Or have you ever wanted to quickly know what the delay time should be for a certain BPM (tempo)? If so, then behold the Delay Calculator! A cool little ditty that you just load up, type in the tempo, and it does all the work, giving you delay times down to a 32nd! Superfast, supersmall, and supereasy to use - that's our motto here at AnalogX! Both GUI and commandline version of this utility are available.

If you've ever done commercials, or worked with doing music for video, then you know how difficult it can be figuring out just what BPM (tempo) to use, and how long it will be. SongTime is a down-and-dirty little app to take the drudgery and guesswork out of figuring it out! Just run SongTime, enter in the BPM, Beats/Measure, and number of measures, and it will tell you not only how long it will be, but also frame and keyframe times as well. Then, just play with the BPM or any of the other parameters, until the time is right where you want it. Both GUI and commandline version of this utility are available.

Have you ever wanted to know exactly what BPM (Tempo) a song was at? Well, there's a better way then guessing, and TapTempo is the tool to do it. Simply run TapTempo, play the song, and press the spacebar on every beat; after a few seconds, you'll see the tempo (along with other info) displayed!

AutoTune analyses sampled sounds in frequency space to allow you to tune all of your sounds to the same frequency! Just simply enter the note you want to use as the base for all of your sounds, such as C3, and then simply drag your samples onto the application, and voila! Let AutoTune do the rest! AutoTune can also be used to convert directories, instead of individual files, by simply dragging the directory onto the app. Now, AutoTune is VERY computationally intensive, so it can take it a while for the analysis to take place, be patient! AutoTune is also pretty memory intensive, using around 6 to 8 megs of RAM for the average file, so the more memory you have, the faster it will run. AutoTune now supports mono and stereo WAV files, 8/16/24/32 bit formats (both MS and IEEE), and can also normalize and DC correct samples!
