Overview

Sound Spectrum Pro is a comprehensive audio analysis tool designed for both professionals and enthusiasts in the music and audio industry. This application offers advanced features such as Real-Time Analyzer (RTA), Fast Fourier Transform (FFT) amplitude display, and sound pressure level measurements in dBA, dBC, and dBZ. With its user-friendly interface, users can easily navigate through various on-screen controls to access functionalities like noise criterion measurement, impulse response analysis, and Total Harmonic Distortion plus Noise (THD+N) calculations.

The app stands out with its lightning-fast FFT capabilities, providing an impressive frequency resolution down to 0.01Hz. It supports multiple window functions, logarithmic or linear frequency axis adjustments, and peak/valley hold features. The inclusion of signal generators, synchronous measurement modes, and loopback functionality makes it an indispensable tool for precise audio spectrum analysis. Whether you're calibrating audio equipment or conducting detailed sound studies, Sound Spectrum Pro delivers professional-grade performance on mobile devices.

This application is particularly useful for audio engineers, acoustics consultants, and researchers who require accurate and real-time audio measurements. Its ability to save/load files and perform full calibration ensures reliable SPL readings across different environments. The large font SPL meter and adjustable exponential smoothing make it accessible even in challenging field conditions, while sharing and printing capabilities allow for easy documentation of results.

Features

Sound Spectrum Pro distinguishes itself through its extensive feature set tailored for professional audio analysis. The application provides both FFT and RTA functionalities with remarkable flexibility - from standard octave to highly detailed 1/24 octave analysis. Its capability to measure Equivalent Continuous Sound Levels (LAeq, LCeq, LZeq) along with specialized metrics like LAeq15 and LAeq60 makes it suitable for environmental noise monitoring and industrial applications.

One of the app's key strengths lies in its sophisticated signal processing capabilities. The lightning-fast FFT engine supports sizes up to 1M, delivering exceptional frequency resolution. Users can select from various window functions and adjust frequency axes according to their specific needs. Advanced features like peak/valley hold, highest peak display, and measurement cursors provide precise control over analysis parameters. The inclusion of multiple signal generators - including tone, white/pink noise variations, and frequency sweeps - enables comprehensive testing scenarios.

Practical usability is enhanced through intuitive touch controls allowing easy pan and zoom operations. Professional users will appreciate the full calibration capability and file management system, ensuring accuracy and consistency in measurements. The application's ability to operate in loopback mode facilitates equipment testing and demonstration purposes. With its ad-free environment and support for high sample rates up to 48kHz (device permitting), Sound Spectrum Pro establishes itself as a serious tool for demanding audio professionals.

Music library size & copyright authenticity

The feature of music library size and copyright authenticity is crucial for any application in the Music & Audio category as it ensures users have access to a wide range of legal and high-quality audio content. Sound Spectrum Pro although primarily an audio analysis tool offers a comprehensive suite of signal generators which can be considered its music library. These include tone white noise pink noise and various types of sweeps and octave noises providing users with a versatile set of audio signals for testing and analysis. The inclusion of these signal generators eliminates the need for external audio sources making the app self-sufficient for many audio engineering tasks. The app's adherence to copyright authenticity is demonstrated through its original creation of sounds using mathematical algorithms rather than sampling existing copyrighted material. This approach not only avoids legal issues but also allows for precise control over the generated sound's characteristics. Users benefit from this feature by having a reliable source of audio signals that can be used for professional audio equipment calibration room acoustics testing and educational purposes. The ability to generate specific frequencies and noise types on-demand enhances the app's utility for sound engineers audio technicians and researchers who require accurate and reproducible audio stimuli for their work.

Audio quality options

Audio quality options are a fundamental aspect of any application dealing with sound as they directly affect the listening experience and the accuracy of audio analysis. Sound Spectrum Pro excels in this area by offering advanced features that cater to audiophiles and professionals alike. The app supports a sample rate of up to 48kHz if the device allows ensuring that high-frequency sounds are captured and analyzed with precision. This high sample rate capability is essential for accurately measuring and analyzing audio equipment's performance and room acoustics. Additionally the app provides a variety of window functions which are mathematical algorithms applied to the audio signal before performing Fourier Transform. These window functions such as Hann Hamming and Blackman each have unique characteristics that affect the spectral analysis's resolution and leakage. By allowing users to choose from many window functions the app enables fine-tuning of the analysis process to suit specific needs. The availability of both logarithmic and linear frequency axis display options further enhances the app's flexibility catering to different analysis requirements and personal preferences. Moreover the adjustable exponential smoothing feature helps in stabilizing the real-time display making it easier to read and interpret dynamic changes in the audio signal. These audio quality options collectively provide users with the tools necessary to perform detailed and accurate audio analysis making Sound Spectrum Pro an indispensable tool for anyone involved in sound engineering audio equipment testing or acoustical research.
