Spectrolite vs Easy Audio Spectrogram

Spectrolite visualizes sound as spectrograms in real time. Spectrolite supports constant-Q spectrograms, which use a logarithmic frequency scale for a display where musical notes are evenly spaced. Spectrograms based on linear and mel frequency scales are also supported. The display covers the full frequency range of human hearing. Intuitive touch panning and zooming lets you dive in and explore the spectrograms in detail. Gain, Q, and other parameters can be adjusted in real time and instantly apply to the display of past signals as well as future ones. The Pro in-app purchase adds grids and scales for time, frequency, and amplitude, as well as a spectrum view and a tap-to-measure function. This expands Spectrolite into an audio measurement tool that you can use to measure frequencies, musical pitches, amplitudes, and durations.

Easy Audio Spectrogram is a simple real-time audio visualizer for microphone input. It shows live spectrogram and frequency spectrum views, helping you explore voices, instruments, music, room noise, and everyday sounds. The app is built around readability. Instead of adjusting gain values in the blind or fight a fixed color range, Easy Audio Spectrogram lets you adjust the graph’s dynamic range in real time. Use the live spectrum display as a guide, drag the color scale to the range you care about, and instantly get a clearer spectrogram. For music and voice, the app includes a note-based frequency scale and real-time pitch detection, making it easier to see sung notes, instrument pitch, harmonics, and resonance as they happen. The interface is minimal and comfortable to use in any orientation, even upside down. Text and icons rotate, but controls stay where they are, so the app remains easy to use whether the phone is in your hand, on a table, or pointed toward a sound source. You do not have to understand what's an FFT to use this app, the default setting works well and engineering settings have been translated to understandable concepts. You can save clean spectrogram screenshots directly from the app, without the buttons covering the image and without pressing hardware button combinations. This app is free to use, free of pop-ups or advertisement banners, use it to explore music or the science of acoustics. Additional Features: -Noise profile removal, hold the button to record a profile, release to activate. -Analyze harmonics in real time with multi-touch. -Psychoacoustic filter to make the graph reflect perceived sound signature rather than flat physical reality. -Optimized performance for many hours of use without heating up your device or draining the battery.
