Audio test tones
When processing time exceeds a second, a progress bar will appear.You choose a name for your sound file or leave the one that is suggested by Make A TestTone untouched, you navigate to a folder where you want to save the sound file, and you choose one of the available sound file formats: AIFF, WAV (BWF).When you have done that, you push the ‘Generate Sound file’ button at the bottom right: a ‘Save’ dialog appears.indicate wether you want the testtone introduced with spoken text (a female voice says, for instance, "one thousand Hertz at minus ten point zero decibel, 44.1 kHz sampling rate.Then you supply the chosen algorithm with a few parameters describing the exact test tone you desire, using the radio buttons and editable text boxes.With the third option it is possible to create the tones and sweeps of the first two and more, but you will need to pass more parameters. First you select one of the following algorithms by clicking on of the first three tabs:.The tones have proven to be a very valuable addition to listening tests with musical and speech fragments. We have, for instance, been using these tones for quality checks of the sample rate conversion, word length reduction and look-ahead compression algorithms in BarbaBatch (our batch sound file conversion package). Why did Audio Ease create this app?Īudio Ease has used the signal generating algorithms within Make a Test Tone extensively in the production of signal processing algorithms. In general, test tones can help detect deficiencies in acoustical, recording, signal processing and wiring situations. There is a variety of situations where test signals come in handy, ranging from standard reference tones preceding recordings (with Make a Test Tone you can choose to introduce the specs of the testtone with spoken word), to measurement and adjustment of room acoustics. In addition it drops markers in the sound files, indicating the exact frequency or amplitude at that spot. It calculates flexible, highly accurate signals that are saved to either AIFF and WAV (BWF) sound files up to 192 kHz.
