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 FFT amplitude display, RTA octave band analysis, 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 real-time displays of audio data.

In addition to its core functionalities, Sound Spectrum Pro provides specialized tools like Noise Criterion measurement, equivalent continuous sound level tracking, and impulse response analysis. These capabilities make it an ideal choice for acousticians, sound engineers, and anyone involved in audio production or environmental noise assessment. The app's ability to perform high-resolution FFT with adjustable window functions ensures precise frequency analysis, catering to the needs of even the most demanding audio professionals.

One of the standout features of Sound Spectrum Pro is its extensive range of analysis tools. The app supports multiple RTA resolutions down to 1/24 octave, providing detailed insights into audio signals. Its lightning-fast FFT processing, with sizes ranging from 16k to 1M, delivers exceptional frequency resolution as low as 0.01Hz when combined with downsampling techniques. This makes it particularly useful for identifying subtle audio characteristics that might be missed by less sophisticated analyzers.

Another remarkable aspect is the app's calibration capability and signal generation options. Users can choose from various window functions and adjust settings like peak/valley hold, exponential smoothing, and measurement cursors. The inclusion of professional-grade signal generators - including tone, white noise, and pink noise variations - along with synchronous measurement modes, enables accurate system testing and analysis. Furthermore, the app's ability to save/load files and share screenshots enhances its practicality in professional environments.

Sound Spectrum Pro offers an extensive music library that caters to both casual listeners and audio professionals. The app includes a wide range of signal generators such as tone, white noise, pink noise, and more, ensuring users have access to all necessary audio tools.

The application is designed with copyright authenticity in mind, providing users with the confidence that all included sounds and signals are properly licensed for use. This feature is crucial for professionals who rely on accurate and legal sound sources for their work.

With its comprehensive suite of features, including RTA, FFT, and calibration tools, Sound Spectrum Pro stands out as a complete package for sound analysis and creation. Users can explore various audio measurements without worrying about copyright infringement.

Sound Spectrum Pro excels in delivering top-notch audio quality options, making it an indispensable tool for audiophiles and sound engineers. The app supports a sample rate of up to 48kHz, ensuring high-fidelity sound reproduction that captures even the subtlest nuances in audio signals.

In addition to supporting high sample rates, the app provides numerous window functions and customizable settings like logarithmic or linear frequency axis, peak and valley hold, and adjustable exponential smoothing. These features allow users to fine-tune their audio analysis to achieve the most accurate results possible.

Whether you're measuring sound pressure levels, analyzing frequency responses, or generating test tones, Sound Spectrum Pro's superior audio quality options ensure that every task is performed with precision and clarity.
