Software Downloads for "Sound Level Indicator"

This project is for matlab development of a virtual sound level meter. The program will read in a .wav file and allow the user to analyze it as one would analyze a sound field with a sound level meter..

This tutorial/demo presents the design of a sound level meter in Matlab. The Data Acquisition Toolbox is used to implement a real-time spectrum analyzer. The decibel meter is implemented in the frequency domain using Parseval's relation. Documentation is provided in the included PDF.

VUmeter is a compact application that allows you to check the sound level received by your sound card using the microphone.

It is designed to help you notice when the sound level spikes and creates distortions in the recorded audio files.

KTDrumTrigger is a VST plugin with custom editor that triggers MIDI notes based on the sound level of the incoming audio stream in different frequency bands. It allows you to "detect" occurrences of percussive sounds in an audio stream and send out a MIDI event whenever that happens..

The Portable Sound Monitor (PSM) is ideal for anyone working within the music industry ( our primary market ) as well as environments where it is imperative to measure the quality of sound, such as motor racing, shooting events and public displays. The main advantage PSM is the ability to be able to forward the recording via email as well as text message. The quality of the recording is somewhat dependant on the ability of the Smartphone microphone. Generally speaking the handsets on the market that make use of Windows based technology tend to be the high end units and therefore tend to also come with a well built microphone.

Sleepy Sound has been designed according to medical recommendations and promotes more deep relaxation before and after sleeping. Try Sleepy Sound after hard working day. Turn on your favorite quiet music from CD or player on computer and launch Sleepy Sound. It will decrease sound level step by step and you relax after him and fall asleep. Then after desired time period Sleepy Sound will increase step-by-step sound level and you softy awake from sleep. Time period before sleeping, amount of sound levels and wake up period choose according your biological rhythms.

DSSF3 Light is a highly advanced sound analyzer greatly exceeding the usual FFT analyzer's performance. It is the best choice for learning sound measurement and for education. It is mainly applicable to a measurement of home audio and a car stereo, for a measurement of an electric circuit, and noise measurement. DSSF3 Light is equipped with the latest functions of therealtime analyzer, such as the signal generator, the FFT analyzer (Power spectrum, 1/1 and 1/3 octave band analysis, and Waterfall), the sound level meter (slow / fast preset), the oscilloscope, the sound recorder.

Sound Level Meter is in the 4th set of the Smart Tools collection (noise).

SPL(sound pressure level) meter app uses your phone mic to measure noise volume in decibels(db), and shows a reference.

REMEMBER!! The smart phone microphones were aligned to human voice (300-3400Hz, 40-60dB). Therefore the maximum values are LIMITED by the manufacturers and the very loud sound(100+ db) cannot be recognized. Moto Droid(max.100), Galaxy S3(81dB), Galaxy Note(91dB), Galaxy S2(98dB)...

See the 4-5nd pictures.

Best Sound Meter (sound pressure level) is an app which can measure the actual sound level meter with dB.
It uses your built-in microphone and shows a reference. We had calibrated many android devices with the actual sound level meter with dB.

You have to know that the built-in microphones were aligned to human voice (300-3400Hz, 40-60dB). Therefore the maximum values are limited by the hardware limitation, and very loud sound (100+ db) cannot be recognized.

Remember that it's only a device for fun and please use it as an auxiliary tool.

The Sound Meter uses the microphone of your phone / tablet to measure the sound level, and display the result on any of the following Sony Smart Accessories:

* SmartWatch 2
* SmartWatch
* Wireless Headset Pro

Besides the actual sound level, the maximal and the average sound levels are displayed at any time.


Disclaimer: the results may be different than what a professional Sound Meter device would measure.
