Features
Read full description

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.

Read full description

Looking for a way to detect frequencies around you? TONE Telegenics is a Frequency detector that reveals the audio frequencies of any environment and displays them in a detailed graph view. Frequencies are the rates at which sound waves vibrate per second, measured in Hertz (Hz). Detecting these frequencies is crucial in various applications, including acoustic research, noise control, and audio production. With TONE Telegenics’s mobile app, you can: REVEAL THE AUDIO FREQUENCIES OF ANY ENVIRONMENT: The app can be used both indoors and outdoors, to capture and analyze the sound profile. It doesn’t limit the user to specific conditions; rather, it adapts to wherever the user is, making it highly versatile. It can be used for tasks such as measuring room acoustics, identifying unwanted noises in residential and commercial areas. DISPLAY THE AUDIO FREQUENCIES IN A GRAPH VIEW: The frequencies detected are not just listed numerically but are also visually represented through graphs. These graphs typically displays frequencies horizontally and amplitude vertically, helping users visualize the intensity and distribution of frequencies. EXPERIENCE SOUND ANALYSIS WITH CLARITY AND PRECISION: This highlights the app's ability to provide clear and precise feedback on sound analysis. Clarity and precision are crucial for ensuring that the frequency data is accurate and useful. Precision in sound analysis is essential for tasks requiring exact frequency responses, conducting research on sound waves or calibrating audio equipment. VISUALIZE AUDIO DATA IN REAL-TIME: TONE Telegenics offers real-time visualization of audio data. This means that as soon as sound is detected, it is immediately detected and visually represented in the app. There is no significant delay between sound input and visual output. Real-time data visualization is critical during real-time noise monitoring, or any scenario where immediate feedback on sound quality and levels is necessary.

Verdict

The call

The clearest difference is in-app purchases: TONE Telegenics at none against Spectrolite's 1. TONE Telegenics also leads on update cadence (every 3 weeks vs every 8 months) and rating (5.0 vs 4.8). Spectrolite's advantage is ratings volume (64 vs 2). On price, ads, device support and iOS requirement there is nothing between them.
