Question

Export audio into various formats with different parameters set and find out the differences in the audio quality.

Answer 1

The recorded interview was exported into different audio formats with different quality settings.

Audio Format	Quality / File Size	Observation
WAV	High quality, large file size	Clear sound with very little loss in quality
MP3 – 320 kbps	High quality, smaller than WAV	Very good sound quality
MP3 – 128 kbps	Medium quality, small file size	Suitable for normal listening
MP3 – 64 kbps	Lower quality, very small file size	Some loss of clarity can be noticed
OGG	Good quality with moderate file size	Good balance between quality and size

Higher bit rate generally gives better audio quality but increases file size. Lower bit rate reduces the file size but may also reduce sound clarity. WAV provides high-quality audio, while compressed formats such as MP3 and OGG require less storage space.
