In the following exercises, you will use the MusicCPR digital audio workstation (DAW) to make edits to audio recordings that you or others have made.
USE PREMADE FILES???
Exercise 1: selecting and de-selecting (creating and removing selection: do not mutate audio file)
Prereqs
have an audio sample: is it because they just recorded or because we have provided some?
Instructions
Remove that region (the highlighted selection) by double clicking it, and then repeat exercise 1 but for a region of silence at the start of the track.
Submission?
Post: Now, listen to your file; what do you notice about the very start? Has removing this region caused the audio file to sound choppy? <-- make question sort of hint that there's no difference
Exercise 2: make selection (select region) and delete/splice selection
Prereqs
have an audio sample, can be a continuation of the previous (prev exercise didn't mutate)
Instructions
(2 parts include removing silence at beginning and at the end)
When making audio recordings it is very common for silence to lead or trail the important audio. The audio file for your recording includes silence at the beginning and the end. We can use the splice and delete tool to remove this silence. and here's how to do so...
Submission
Post: Now, listen to your file; what do you notice about the moments leading up to your deleted region. Is this version an improvement to your recording, or do you feel it is worse?
Exercise 3: select and retain
Prerequisite
have a recording where silence hasn't been trimmed yet:
do we tell the student to click undo (this is its introduction)?
or instead does this step come on the record bassline (which they will only be able to do after the record melody that has the prev exercises included/embedded)?
Instructions
We will now accomplish the same goal above but with an alternate tool: the splice and retain tool. Unlike the splice and delete tool, this tool retains only the region that was selected when the tool was used, and
Try to delete the regions of silence at the start AND end of the following audio file by selected using the splice and delete tool.
Submission
Post: What did you notice about the operations themselves - how efficient are they when compared to each other, that is, did the computer take longer to complete the 1-step approach of exercises 1 and 2. !!! in exercise 3 vs exercises 1 and 2, that is, s the moment of cutoff sound !!!! cuts sound more, less, or equally abrupt?
will they notice how long the thing takes, or should we provide text to let them know? or else ask differently?
efficient in terms of cpu time/space/effort vs. in terms of human actions/cognition, ability to use the peripherals
Exercise 4: EQ - amplify frequency range
Where do we embed this one?
Prerequisite
specifically useful audio sample: @hcientist proposes that we trim the sample of the melody and then artificially quiet it down, and then combine it with their just trimmed (retained) bassline, and have that be the input to this exercise
Instructions
The bass voices in the following recording lack presence/volume. Try to use the equalizer to bring out those lower voices and quiet some of the high voices.
Post:
Exercise 4:
The following recording What do you notice about the quality of sound after making edits? are the timb the equalizer effects?
Exercise 5: Exploratory:
Try to use the equalizer widget on the following file to bring attention to different voices in the ensemble.
