Adding Audio Effects

1.  Altered Studio has a number of effects and edits which allow you to perfect your voice file without using a separate editor.

2.  To add a new effect at any time, select the relevant section of the waveform or transcription which you wish to apply the effect to, and either (i) right click on the waveform and choose Add Effect, or (ii) click on the last layer in the History panel and then click the + Effect button below this layer.

3.  Effects will be applied to all or a selection of the audio file, depending on what selection of the transcription or waveform is made when the effect is added. Where no selection is made the effect will apply to the entire file.

4.  Effect layers only change the section of the waveform that was selected when the effect was added. Where a selection is used to add an effect and you then wish to add a new effect to a different section of the waveform, you should click on the last layer in the history, select the new section of the waveform or transcription, and add a new effect layer. The timecode for each effect is displayed next to the effect name in the History panel.

5.  Effects and edits can be performed at any time, however as noted above it is recommended that these are carried out prior to any Morphs being added, to avoid the need to unlock the History and make antecedent edits. Refer to ‘Working with the History – Advanced Mode’ for more information.

6.  The Resample effect allows you to change the sample rate of your file. The speed of your file will not be impacted unless the Fake Resampling switch is set to On, in which case resampling will also affect the speed and pitch of the audio file.

7.  The Passthrough effect has several options (Mix, Loudness and Crossfade) which are described below. The options apply to the Passthrough effect and also when Morphs or pasted audio are added to the waveform when they will be displayed in the Mixing panel on the right of Altered Studio.

8.  Mix allows you to choose how audio will mix together. The options are Insert, which will shift the waveform to the right and add the new audio before the original selection; Replace, which will remove the original audio and replace it with the new audio; and +Mix, which will mix the new audio with the original audio.

9.  All three Mix settings have controls to adjust the number of repeats and crossfade of the mixed sections. The +Mix option also has controls to adjust the gain and balance between the two pieces of audio which are being mixed.

10.  Loudness allows you to adjust the volume of your audio and has three options. Apply Gain will adjust the gain based on the chosen settings and includes settings for Relative, Absolute and Peak Normalise. Match Existing Loudness will match the loudness of the original section of audio (this will not be available when Mix – Insert is used as there is no existing audio to base the gain on). Match Surrounding Loudness will take the loudness from the surrounding audio and can be adjusted to take more or less influence from audio before and after in the waveform.

11.  In each of the three loudness options, gain can be set using either RMS power or LUF loudness. Additionally the gain adjustments can be faded in and out as required.

12.  Cross-Fade allows you to adjust the fade in and out of a selection, or of the whole file. The options are No Cross-Fade, which does not apply any crossfade effect; Linear Cross-Fade, which applies the fade in a constant manner; and Sine Cross-Fade, which apples the fade base on the sine wave. The Fade-In and Fade-Out durations can be adjusted separately for each option.
