If you encounter the same processing flow at work and process the same piece of audio to see if the processing results are consistent, you can use audacity to process it.
Assume that the audios to be compared are 1.wav 2.wav
1. Open 1.wav with Audacity
2. Open 2.wav with Audacity, select the audio, and then use Effect->Reverse (up and down)
3. Use Audacity Track-> Mix -> Mix and render to new track
4. Look at the mixing effect. If the change is the same, the difference should be 0.
