The start screen is where you play either the preset or your own saved sessions. The audio can also be exported in MP3 / M4A / WAV format to your music library.
All sessions have a default length they were created with but this can be changed using the time selector before you start playback or export (anything from 1 minute to 24 hours). From here you can either edit an existing session or create a new one.
The Settings button allows you to pick the folders to use for your saved sessions and imported audio.
The Editor page is where you define the entrainment frequency’s for the session. This is done by adding nodes which also contain the volume levels of each sound.
You can either start here or go first to the Sound Mixer to setup the sounds and entrainment type you would like to use.
(1) Locks the nodes to the X axis. They can then be freely moved in time without changing the frequency
(2) Aligns the selected node to the same frequency as the nearest node to the left.
(3) Allows nodes to be deleted.
Play: Starts/Stops playback. For a newly created session you will not hear anything until you setup the sounds. You can drag the play bar to any position.
Sounds: Navigates to the Sound Mixer
Frequency: Opens/Closes the frequency selector panel. You can select a specific frequency or type in a value. Entering a frequency higher than 40Hz will resize the canvas.
Levels: Opens/Closes the levels panel. The entrainment tone pitch is automatically calculated from the slope settings in the Sound Mixer-Tone page. This can also be overridden for each node, for instance you may want to experiment with the Solfeggio frequencies.
The volume levels for each sound allow you to create variation as the session plays to make it more interesting. For example, if you add two different rain sounds, to fade between them set:
Node 1: Rain 100%, Light Rain 0%
Node 2: Rain 0%, Light Rain 100%
Length: For new sessions the length is set to 30 minutes. You can change the time to any value.
Save: Saves to the folder defined within the settings options on the start page. If no folder has been set you will be asked to select one. A name and description of the session can be added.
(1) The Sound Mixer contains 4 pages:
Background: Continuous looping or sequenced sounds
Incidental: Single sounds that are set to play randomly
Tone: The entrainment tone settings
Master: Sets the master volume, fade in/out time and sequencer tempo
The VU meter at the top left shows the overall level. If this goes into the red you will hear the audio start to clip so you can either turn down individual channel volumes or just turn down the master volume.
Adds a new sound channel to the background or incidental list
Opens the sounds selection list. These are split into continuous looping, single (e.g. piano) and user (requires that you set a folder that contains your own audio files on the start page options).
This section shows the mixer settings for the selected sound.
For background sounds the first row has:
Modulation: Adds isochronic modulation to the sound. This can either be set to a subtle amount or if set to full will replicate the isochronic tone.
Pan: Positions the sound left or right.
For Incidental sounds the first row has:
Random: Sets how often the sound will be played. A setting of “1 in 1m” will play the sound approximately 10 times within 10 minutes.
Random Pan: If checked, when the sound plays it will appear at a different position each time in the stereo field.
The Pitch sliders change the pitch between -2 / +2 octaves.
The Low pass filter removes high frequencies from the sound and the High pass filter removes low frequencies. These can be used to tailor the sound to your liking, for instance removing some high frequencies will make it sound more distant.
This section contains 4 echo effects that are shared between the sounds. Each sound can be sent to any of the units (they need to be switched on first) using the Amount sliders. The Time slider sets the period between the echo’s and Feedback is the amount of signal which is sent back in. If this is turned up it will take longer for the echo’s to decay. The ( ) button switches the unit to stereo mode and you are given an option for the stereo width. The filter switches between Low pass to the left and High pass to the right. If turned to the left more high frequency content will be filtered out of every repeating echo.
You can either select to use an Isochronic Tone or Binaural Beat. For isochronic set the volume to a level that you are comfortable with. For binaural the volume just needs to be heard slightly above all the other sounds.
The Modulation shape slider changes the wave shape which effects the isochronic tone and background sounds for when you add modulation. It morphs between sine (softer) and square (more pronounced).
The Pitch High/Low sliders change the slope of the tones pitch. When the entrainment frequency moves up or down the tones pitch is calculated from these settings. The tone pitch can also be overridden for any node to make it constant.
For isochronic tones there is an additional option to add noise to the sound with a variable amount of modulation.
Processing options for the background sounds
This simply loops the sound and is the most common and quickest method to use.
XWave adds an additional audio processing option for background sounds which can help remove the repetitive nature of audio loops without the need to have large amounts of sound data.
Two waves are started from a random position within the selectable window and are faded between each other to reconstruct a continually changing sound. The Fade and Length controls set the fade in/out and sustain length in seconds for each wave. The Alternate stereo button causes each wave to have a reversed stereo image.
The step sequencer allows single notes or chords to be played in a rhythmic pattern.
The + button adds a new step. If you have the last step selected it will add 4 steps at once.
Each sequence can have an independent speed which is between 1/64 to 8/1 of the BPM (beats per minute).
If you are using a keyboard the up/down arrow keys can be used to navigate.
Each step shows space for 4 notes, a bar showing the length of the step the notes should be held and the step volume.
The different play modes are:
- Down / Up
- Random – no repeat
- Random, then random number of steps down
- Random, then random number of steps up or down
The Edit button will enable adding notes from the piano keyboard into the selected step. The green bar at the bottom of the keys shows the notes in the selected musical scale and key.
The Chord button allows selection of either single note entry or simple 2 to 4 note chords.
The Length button sets the note length on entry but this can also be changed with the Set button:
This changes the steps volume and note length as a fraction of the step length (between 25% and 100%), or it can be set to Hold where the notes will continue until either a step with Off or containing notes is hit.
The envelope controls how the sound changes in amplitude over time.
The Attack/Decay and Release values are set in seconds. The Sustain is set to 0-100% of the amplitude.
The envelope shape is analog modelled (exponential shaped sections rather than linear) to give a more natural response.
When a note is triggered it passes though the Attack and Decay and holds the Sustain for the length of the note/step which then starts the release.
The waveform window sets the random start position of the sound. Use the left/right markers at different positions to add some variation or both at the same position to always play from the same position.
The volume tracking compensates for the way out ears hear higher pitched sounds louder than lower pitched sounds. Moving the slider to the left will increase the volume of lower notes and decrease the volume of higher ones.
The Loop button should be switched on for looping sounds. If it is on for single sounds and the envelope is long enough the note will repeat which may or may not be desirable.
