Question 1

How do I calculate audio file size?

Accepted Answer

Bitrate × Duration. 320 kbps MP3 for 3 minutes = 7.2 MB.

Question 2

What is a good audio bitrate?

Accepted Answer

MP3: 128-320 kbps. FLAC: 800-1400 kbps. Higher bitrate = better quality.

Question 3

Why is my storage smaller than advertised?

Accepted Answer

Manufacturers use decimal (1 GB = 1 billion bytes). Operating systems often use binary (1 GB = 1.07 billion bytes). This ~7% difference explains 'missing' space.

Question 4

What's the difference between bits and bytes?

Accepted Answer

1 byte = 8 bits. Storage is measured in bytes (GB, TB). Network speeds are usually in bits (Mbps, Gbps). Divide Mbps by 8 to get MBps.
