PassMark SoundCheck™ is a Windows based application that allows users to test their PC sound card, speakers and microphone. Verify that your sound card can record and playback sounds at various audio sample rates. Speaker cleaner app is a very simple frequency generator which generates different frequencies and performs a sound test and audio test on your speakers. Frequency based Speaker Analyzer It generates a simple sine wave frequencies which will let you test the quality of any kind of speakers.

Testing audio systems doesn’t have to require an expensive consultant, laboratory, or the quietest room on earth. These speaker testing apps help you accomplish that.

Speaker test and tuning mobile apps make it easier for you to get the most out of the space with the least amount of work or gear — all you need is your smart device.

A word of warning: for the most accurate results, you need to be using a professional USB mic to take audio measurements with your mobile device.

Be prepared to tune a spectrum of different speakers, monitors, subwoofers and acoustical environments with your smart device.

Helpful hints for using speaker testing apps

When preparing to tune a speaker system, it is important to have the capacity to not only gauge a variety of frequencies, but keep track of readings and guarantee that your readings are accurate.

Mobile speaker tuners and testers can accomplish a handful of different readings and tasks. Some apps are focused on low end frequencies.

Subwoofer testers are great for reading frequencies from 0hz and 440hz. Other audio tools with RTA or FFT features can read SPL and help you tune your speakers according to reflection and sound dispersion.

Tuning a space means taking into account not only what is heard on stage, but how the audience hears the performance or application as well.

Having a mobile option for reading sound levels that is multi-functional and accurate is important to guaranteeing the most of the space.

When dealing with specifics, such as speech intelligibility, it is key to being prepared to deal with any application of sound with ease.

Another essential feature that mobile speaker test and tuning apps offer is the ability to save, graph and export readings.

While this does not directly enhance or detract from the apps ability to read sound levels, being able to return to previous readings or send readings elsewhere is paramount for consistency within a specific space over a long period of time.

You want the space to sound good all the time, not just once, and having reference to previous levels lets you confidently say that your space sounds great.

This collection of apps showcases a group of speaker testing and tuning apps for your mobile device.

Each app is useful in specific situations — while every app might not be for you, there are guaranteed to be a few that you will find valuable according to your task. Finding the right audio app is completely up to your specific situation.

Additional resources for IT folks testing audio equipment:

Create your own audio measurement systemstarting with TrueRTA software and your Windows PC. Then add a measurement microphone and USB interface and you have a full audio/acoustic test setup. Start with the free level 1 edition which provides a 1 octave spectrum analyzer, a dual trace oscilloscope and a signal generator. Level 1 never expires. Once you get to see the power of the software and how easily you become productive with it you will want to upgrade to a higher level with greater resolution. More...

Brent Butterworth writing for Sound and Vision Magazine, Jan 2011 :

'While lots of audio measurement software applications exist for the PC, the one that seems to have captured the hearts of engineers and enthusiasts is TrueRTA, available at trueaudio.com. Most speaker engineers I know keep a copy on their computers.'

As an experienced electronic musician holding degrees in music and physics I have a lot of frequency analyzers at my disposal. TrueRTA is simply the best! It is feature rich and simple to use. The display is the most readable of any analyzer I have used. I always have it running when I am working on my music or recording and processing LP records. Kudos to the True Audio team.
