Is there a way to limit the maximum volume level during playback? Sometimes I'd like to increase the volume level to maximum so that I can hear a whisper in the recording, but I oftentimes hurt my ears because loud sounds are mixed into the recording.
If your trying to hear just breath sounds, whispers, etc. Without blowing out your eardrums when the louder portions play.
You can apply compression to accomplish this. It will degrade sound quality overall. However, if your just seeking to locate unwanted noise like breath sounds to silence. Or want to hear sound that exists in areas of very low volume.
You could apply "High" Compression for listening purposes. In most cases, you would remove the compression before producing the video.To restore its quality.
It would be easier in most cases to export the audio and edit it in a program like Audacity, then it would to do the work in Camtasia.
That being said This image shows a audio track at 100% volume level. Its a recorded phone conversation. The purple areas are breath sounds primarily. Peak volume is all over the place in yellow.
In this image, Compression has been applied using "High" as the setting. The near silent areas are much louder. Peak waveforms are flattened out.Their volume overall is much lower.
