Question

Demonstrate various effects using an audio clip, export all audio files with all these various effects applied.

Answer 1

Using an audio clip in Audacity, I applied different audio effects and exported each edited audio file separately.

Effect Applied	Observation
Amplify	Increased the loudness of the audio.
Fade In	Sound gradually increased from low to normal volume.
Fade Out	Sound gradually decreased towards the end.
Echo	Produced a repeated sound effect.
Change Pitch	Changed the pitch of the voice without changing its duration.
Change Speed	Made the audio faster or slower.
Change Tempo	Changed the speed without greatly affecting the pitch.
Noise Reduction	Reduced unwanted background noise.
Reverb	Added an effect similar to sound heard in a large room or hall.

After applying each effect, I used File → Export in Audacity and saved the audio files with suitable names such as Amplify.mp3, Echo.mp3, FadeIn.mp3 and NoiseReduction.mp3.

This activity helped me understand how different audio effects can be used to improve or modify the quality and presentation of an audio clip.
