How can I replace a part of the audio from and to a specific time with

other audio/sound (I want to replace it with beep in this case)?
Here is an example:
ffmpeg -lavfi sine=500:d=10 -y audio1.wav
ffmpeg -lavfi sine=2000:d=10 -y audio2.wav
ffmpeg -i audio1.wav -i audio2.wav -lavfi
[0]volume='1-between(t,4,6)':eval=frame[a];[1]volume='between(t,4,6)':eval=frame[b];[a][b]amix
-y out.wav
That is never going to give smooth transitions.
Also overly complicated as can be simplified with commands to to amix filter.
If my example is too complicated, then please show a simpler example.
