Scale

      Scaling allows you to amplify or attenuate the volume of a selected block or the entire sound file. The scaling factor controls the level of amplification or attenuation. For example, scaling factors set below one result in signal attenuation (turning the volume down), and factors greater than one cause signal amplification (turning the volume up). Be careful when you amplify the sound, because parts of the audio that may be "sticking out" before scaling could clip if the scaling factor is set too high. To avoid this mishap, You can use the find maximum gain and the program will set a limit so that no clipping will occur after scaling the file.

Maximize

      Maximize is much like scaling in that it amplifies the volume of an audio file. Maximize raises the volume of the sound file to its highest point without clipping the audio. A benefit of using this function is that sometimes there are imbalances in a sound file’s volume, and using maximize could "balance out" the entire file.

Mute

      To use the mute function from the toolbox menu, select the block of audio that you wish to silence, then click on mute from the toolbox menu.

Reverse

      This option allows you to reverse an entire signal or a fragment. This is especially useful in certain instances. For instance, you may derive superior results through reverse-time that are superior to what can be achieved through normal processing. Sometimes, when you are Declicking a sound file, you may get better results after a regular Declick, by reversing the sound file and then Declicking again. This is because, the shape of a wave file at the beginning of a noise disturbance like a click could sometimes be more defined when it is reversed. Therefor, the program will recognize more noise disturbances, and the quality of the result file that was reversed will probably transcend the quality of the file where reverse was not used.
      Reversing can also be used for more recreational purposes, such as revealing hidden backwards messages embedded within songs and music. These types of messages where especially popular among the counter-culture groups of the 1960’s and 1970’s.

Compare

     Compare is used to compare the difference between a restored file and a renovated file. Make sure the destination and the source file are open, and then choose compare from the toolbox menu.

Mix

     Mixing is used when you what to combine two files together. You get the effect of two sources of music playing simultaneously.

1. To mix two files, open a file and designate it as the source file.
2. Open the second file and designate it as the destination file.
3. Now open the toolbox and click on the Mix function.
4. You can adjust the settings and audition the mix before you process.
5. Click process when you are satisfied with your results.

Split

      This is used to separate the channels of a stereo recording into two mono sound files containing the left and right channels of the original file. This is especially useful when you want to work with only one channel of a stereo recording.

Unite

      This is used to combine two mono files in to one stereo file. The resulting file contains the information of the mono files in the left and right channels (one mono file goes to the left channel and the other file goes to the right channel to form a stereo file).

Mono

      This allows you to convert a stereo sound file into a mono sound file by mixing the left and the right channels.

stereo

     This allows you to convert a mono sound file to a stereo sound file. By duplicating the mono track.

How to use the filters

Lowpass filter can be used to remove the high frequency components of the signal starting from a desired cutoff frequency.

Highpass filter allows you to remove all low frequency components of the signal up to a desired cutoff off frequency.

Bandpass filter can be used to remove from the analyzed signal both the low frequency components and the high frequency components.

Bandstop filter can be used to remove from the analyzed signal the mid frequency components. These are the frequencies between the high and low cutoff frequencies

Notch filter is designed to remove the components contained in a very narrow frequency band centered at a given notch frequency from the analyzed signal. It is very useful in removing narrow band interferences due to the power supply or electrical coupling. How to use these filters:

1. Depending on what type of frequency you are wanting to surpress you will use one of these filters.
2. Open up the sound file that you want to work with.
3. Select the appropriate filter.
4. Make the appropriate adjustments to the settings and audition the settings using the real time processing.
5. Click on the process button

How to change the sample rate

Resample:
Resample is used when you want to change the sampling rate of a sound file. For example, you might have a file that is in 22 kHz and you may want to change it to 44 kHz. You can use the resample tool to do this.

Adjust Sample Rate:
Adjust RPM Rate allows you to convert an audio file from one RPM rate to another. For example, if you do not have a turntable that supports 78 RPM recordings you can convert the audio file into 78 RPM after recording from the record player.

Trim Length:
Trim length allows you to speed up audio data of an entire compilation without audibly changing the sound of the music (changing the speed by more than 5% may damage the quality of an audio file). This is used when you have a number of songs that you want to write to CD, but you pass the limit by a minute or so. Trim length will speed up the audio just enough so that you can fit all of the songs on the CD that you want without audibly distorting the sound files.

CD Format:
CD Format converts all of your wave files into 44kHz and 16 bit which allows them to be written on to CD.

How to use the Find Pattern Function

Find Pattern is a great tool to use when trying to detect noise disturbances throughout a file. Noises like thumps, clicks, pops, and scratches are commonly identical in their wave form and repetitive throughout the audio file. Find pattern can be used to locate these disturbances so superior restoration can be achieved.

1. To use the find pattern function, select a block of audio, at least 50 samples and no more than 500 samples, that you want to locate throughout the audio file.
2. Click on the toolbox menu and click on find pattern.
3. When the find pattern dialogue box opens, click on the get button to load the pattern in to memory.
4. Adjust the accuracy factors according to how discriminating you want the find pattern function to be when looking for identical bits.
5. Use the arrows to search for the next available identical audio bit in the sound file.

NOTE: You can work with the audio file while the find pattern dialogue box is still open. Minimize the dialogue box when you need to work with the audio file
