With this method you create an exponential frequency sweep ranging from 5 Hz to half the samplerate of your choice. Be sure to fully document the reference tone(s) of your choice. This will allow for future fade-ins of background noise, and, more importantly, this is a safe margin for any copying effects that can occur due to the layers of tape being wound on top of each other. If you put one or more reference tones before a recording, make a 20 second silence between the tone and the program material. These values are standard frequencies for adjusting equalization, bias, levels, tape speed and azimuth on analogue tape recorders, but are still often used in the digital domain. Classic values for such a tone are 700 Hz, 1000 Hz, and 10000 Hz, all at -10 dB and lasting 10 seconds each. A standard application for these tones is the reference tone that is often required preceding recorded material on tape or disk.

You can only see these marker when the soundfile is opened in editing software that recognizes markers. A marker is dropped at the start and the end of the resulting soundfile, listing the toneвЂ™s parameters.

For the samplerate you should choose the rate of your digital program material. The tone will be invariable in both amplitude and frequency. We will now go through the three algorithms, their parameters and their applications one by one.ДЇor this tone you need to choose a frequency, a level, a length and a samplerate. Since the starting phase of the generated sine is always 0, a fade in is not needed. A linear fade out of 0.5 ms is applied in order to avoid a click at the end of the file.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 вЂGenerate Sound fileвЂ™ button at the bottom right: a вЂSaveвЂ™ 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?ДЄudio 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. Make a Test Tone is a generator of sinusoidal audio test signals, and spoken phase checks for speaker configuration up to 10.2.
