Volume over time
Showing the recording's volume over time gives extra feedback that recording has started.
Volume over time during a recording
Usage
Visibility of the peaks and troughs
Make sure the peaks and troughs of the volume are clear and easily distinguishable
for professionals to recognize patterns in the sound
Avoid displaying volume with blurry or indistinct peaks and troughs,
which can make it difficult for professionals to recognize sound patterns
Whitespace between the waves
Create enough spacing between recording waves signaling pauses between
words
Don’t allow the audio to become a continuous wave as it doesn’t communicate
pauses while talking
Applying color
Color match the volume over time with the timer and delete option for
visual balance
Try to avoid using too many different colors within the recording container
