FL Studio Mobile
Use the Analyzer module to visualize important aspects of your music including the Frequency Spectrum, Waveforms (Scope), Loudness (according to various standards), Stereo imaging and Pitch.
Select visualizations by tapping the labels below the display. Where available, the Magnifying Glass icon allows you to zoom in on specific area of the display. The Freeze icon stops motion so you can better see transient details. The controls to the right will change depending on the visualization as explained below.
Some displays will allow you to Zoom or Inspect points:
- How to zoom - Tap the magnifying glass icon to enter Zoom mode. The white rectangle shows the current zoom area. Drag the circles (handles) on the corners to change the size of the zoom area. Tap in the middle and drag the rectangle around to change the position of the zoom area. Double-tap to reset zoom to default. Double-tap again to reset zoom to maximum value. Double-tap, yet again, to reset zoom to your custom value.
- On inspection points - Drag your finger left or right on the graph to see the value of the function at any point. You don't need to be on the display lines, just inside the graph area. The spot-marker will follow the curve at the position of your finger. To remove the marker - simply swipe it off to the side of the graph.
Displays peaks in the audio signal as a function of frequency (along the horizontal axis 20 Hz to 20 kHz). Tap the display and drag left/right to inspect a specific value at the desired location.
- Mode - Choose 2D or 3D views. The 3D view shows spectra over the last 5 seconds (rear-most).
- Scaling - Choose Logarithmic (which gives more detail to the lower frequencies) or Linear scaling for the Frequency axis.
NOTE: The spectrum uses a +4.5 dB/Octave scaling (crossing unity gain at 1 kHz) to increase the apparent level of the spectrum as frequency increases. That is, a 'true' flat frequency response will appear to rise in level along with frequency. If you mix for a visually flat response, this will de-emphasis higher frequencies and accentuate lower frequencies (bass). In this way, a frequency response that 'sounds' flat or balanced, will look more like it sounds. This system avoids the high end of a mix sounding too bright or harsh. As usual, we recommend mixing with your ears, not your eyes and to use this tool as a guide.
Shows the waveform created by the audio signal. The horizontal axis represents time, the vertical axis amplitude.
- Threshold - Lower values are better for visualizing musical content and higher values percussion.
- Time window - Tap the Zoom icon to enter the zoom mode and drag the circles (handles) to move the right-side vertical bar left or right. Move the window left to see more detail in the waveform (to inspect waveform shapes). Move Right to see more cycles in the waveform (best for percussion). The Trigger Point origin can be moved horizontally (in the first half of the zoom range window). This sets where 0 ms, the Trigger point, will be placed on the horizontal axis. Move it to the Right to see more of the waveform before the Trigger point and left to see more of the waveform after the Trigger point.
How triggering (synchronization) works - The display refreshes around 60 times per second. For each update the oscilloscope tries to align the waveform image of each successive frame, so the image appears stable. The oscilloscope uses a rising edge detection to perform that task. That is, a snapshot of the waveform is taken each time the threshold is crossed for the next window period. The level that triggers the detector can be set using the Threshold slider. The detected edge is aligned with the 0 ms mark on the x axis.
Shows loudness according to several metering algorithms. Apart from 'Peak' and 'True Peak' all the other metering algorithms apply some 'average', 'weighted average' or 'secret squirrel mathematics' to better represent 'loudness' as perceived by humans (that's you).
There are three displays allowing you to monitor the stereo width (Vectorscope), stereo interference (Correlogram) and panning (Balance) of the mix.
- Vectorscope - The central part is the vectorscope. The sound 'flower' shows stereo width of the audio. The wider the display the more stereo signal is present. For mono signals it will display a single petal (vertical when panned to center) or leaning to one side (L or R) when panned. For stereo signals the goal is to keep the 'flower' within the central sector delimited by the L and R safety lines. If the 'flower' is wider than the central sector, it means that the Left and Right channels are out of phase, i.e. they will cancel each other out when they are mixed together (on a phone's mono speaker). This can sound heavily distorted. Its bad, don't do it!
- Correlogram - The graph in the top left corner is a correlogram. It shows interference between left and right channels. Two parallel lines means that the Left and the Right channels are in phase. If you see that lines have crossed and the gap between them is filled, the channels are out of phase. If channels are out of phase it means when the Left speaker is pushing, the right speaker is pulling, which will cancel out to a weak sound, lacking bass, if the audio is mixed to mono.
- Balance - The small white dot running around the arc is the balance indicator. It shows how the audio power is distributed between the Left and the Right channels. On the master channel, normally, you would want to keep the balance in the center when the whole mix is playing.
NOTE: The information above is advice, its not RULES! Sometimes you need to ignore advice to achieve artistic goals. Most importantly, you need to learn what sounds good, and how that relates to what you see on the display. Eventually, you will know what to look for, or watch out for.
This is a Monophonic pitch tracker similar to the Tuner module. In this case a rolling-history of detected pitches is displayed.
NOTE: This does not work with complex polyphonic musical material. It is best suited to monophonic sounds.
- Reference - Change the Tuning reference from the default A440 Hz.
These are global settings.
- Channel - Choose the Left + Right, Left or Right channel to monitor. Most display modes are Monophonic, and so only one channel is needed to create the visualization. Try selecting a single channel when displays appear less stable or glitchy.
- Reactivity - How quickly various visualizations respond to the input signal.
- DC Block - Filters out DC offset to the input signal. DC offset is where the waveform averages above or below the 0 dB line, is offset from it. DC offsets can interfere with various algorithms used in the visualizer.
- Input gain - Input level. Increase where you are trying to visualize a weak signal.
