For music fans, add some colour and great visuals to the experience with Audio Lab. It is a music visualizer that offers volume, pitch and beat detection.
Turn on some music and watch the balls bounce off each other in Mosh Pit, explore alien worlds with World Explorer, be dazzled by the explosions in Flocking, bop to the beat with Beat goes on, Rainbow and Leafy ... or just chill to some colourful clouds.
You can get to options and controls by swiping in from the right side of the screen, or double tapping the screen. Touch the main screen to make it disappear.
With 50 unique visualizers there is plenty to choose from. Here is a few -
✔ Mosh Pit shows bouncing, colliding spheres. The bounce is dependent on the volume and pitch of the notes played.
✔ World Explorer shows a solar system of small planets that is travelled. Colours of the next planet to be visited are selected by notes played. The nodding is dependent on the beat.
✔ Photo adds a personal touch allowing you to view your photos, initially showing black and white, colours are chosen from notes being played. You can choose the directory the pictures are displayed from in the options.
✔ Concho shows a nice spirally effect, with each spiral representing a note played and the sideways movement following the beat.
There is a selection of tools as well as the playful visualizers. Tools include -
✔ Input, shows the original sound wave.
✔ FFT shows the resultant frequency wave.
✔ dbFS shows volume across frequency's.
✔ Notes displays recognised notes. Great for singers to show what notes they are hitting
✔ Beat detection shows BPM. This is calculated over time. It could be used by drummers to try and hit a constant BPM ... and then improve their score.
Controls include -
✔ Select a visualizer, mark it as a favourite
✔ Cycle visualizer, tools or favourites
✔ Some visualizers have their own settings, especially see photo visualizers that allow you to select the photo directory to display
✔ Capture can use the current Audio stream, or the microphone. Mic is more accurate but uses more processing power
✔ Media controls
✔ Display shows the current visualizer
Note that the app can use microphone input that can detect external music being played, but it's at its best when music is played via the same device.
