TextEdit that comes with Mac OS X doesn't always save in a plain text format. There is a text editor in the program, or you can use your own, like BBEdit. We do have returns in our data portion, but as we have not defined them to map to any tones, they cause no additional output. Then we have the letter h, which is a macro, which means that the tones for buttons 8675309 are sent. In this case we are sending each tone tone button's tone pairs, with a space between them,Īs s was defined to be a 1 Hz tone of amplitude 1%, making it inaudible. This means that whenever the character h is encountered, to substitute the characters 8675309 instead.ĭon't define a macro using a letter already assigned to a tone.Īfter the macros have been defined, there should be the following line:Īnd following this, the text to be converted into tones. Macros are easy to define, in our example, we have one macro definition: You must include this line, even if no macros follow. You must specify all three values for each, including both amplitudes, even if the sound file is monophonic.Īfter all of the tones are defined, you define the macros, preceeded by the line: You can define up to ten frequencies for each character. You can have different amplitudes for each tone and channel of course, but for a given channel, the sum of all the amplitudes for all the frequencies should not exceed 100%, or distortion will result. The next set of three values is 1209 50 50 which means we want to play a second tone at the same time, of 1209 Hz, also 50% amplitude in each channel. The 697 means to play 697 Hz, the 50 50 means to set the amplitude to 50% for both the left and right channels. Next, we take values in blocks of three, such as 697 50 50 in that line. The second value is the length (in seconds) that tone should be played for. That is, you use the tilde here to define the tones to send The first letter in the line is the character assigned to that tone.Īny printable or non printable character may be used, except for the tilde ~ which isĪctually mapped to the space character, since it is more likely you will want to define For example, the definition for the 1 button:Ĭharacter length freq1 ampL1 ampL2. A tone can actually be defined to produce more than one frequency at a time, which is necessary in cases like DTMF where two tones must be played at the same time for each button on the phone. Each tone is assigned to a character, whenever that character appears in the fourth section of the file (tones to send) it is produced. Sampling is the sampling rate in Hz, such as 44100, 11025, 8000, etcīits is the sample size, only 8 and 16 are allowedįileName is, as expected, the name of the file to produce #format fileType sampling bits channels fileName The first line defines the format of the file to produce: There are four sections to the file:īelow is an actual file, let's take a look at it: PAG reads in a text file to define what audio to produce. Let's say you wanted to make a file of DTMF (Touch Tone) tones to test out some equipment. PAG is useful for creating files of test tones, for testing audio software, or equipment.
