The lack of user-friendly analyzers has made it difficult for musicians and other sound-based professions to reliably optimize the clarity of their performance. Despite the availability of digital sound conversion and optimization solutions in the market, only a handful of devices can detect the sources of interference anywhere. It is also important to ensure that sound quality is evenly distributed and perceived to be acceptable throughout the venue. The measured power distribution over various frequency ranges can be used to tune and arrange musical equipment to optimize the sound quality experienced by the audience.
The Handheld Spectrum Analyzer is a device that analyzes the spectrum of input sound sources received from either audio equipment or the surrounding environment. In addition, the device allows the user to move throughout the working area and observe the different power distributions of the sound spectrum. The proof-of-concept prototype for our Handheld Spectrum Analyzer should be able to accept surrounding sound as input, calculate its frequency spectrum and display its corresponding power bar graphs on the display unit. Furthermore, the device’s interface will tentatively have other features, such as allowing the user to save and store captured spectrums for future comparisons.
