How many songs can take 4g?

Answer 1

This is a hard question to answer.

It all depends on how large each song is. Each song will be a different length, so that will effect the size of the song. Also, the songs may be encoded with different compression methods, so you have to take that into account.

A song encoded using the MP3 codec with a bit rate of 96Kbps at a sample rate of 32KHz will have a smaller file size than the same song using the same MP3 codec with a bit rate of 320Kbps at a sample rate of 48KHz.

Also, a song using a specific set of encoding specs (bit rate, sample rate, etc) encoded using MP3 will be a different size than the same song with the same encoding specs using the AAC codec.

The best thing to do is to average your songs by size per minute.

Take your song size and divide it by the songs play time (use seconds instead of minutes), then you'll know how many megabytes per second your song is. Multiply that by 60 to convert to minutes.

Once you know how many megabytes per minute your songs use, then you'll know how many minutes a certain size memory card can hold.

Example:

Song Length = 5 minutes

Song Size = 5 Megabytes

Time in seconds = 300

Math Part:

5MB divided by 300seconds = 0.017 megabytes per second

.017 multiplied by 60 = 1 MB per minute

You have a 4Gigabyte memory card.

1 GB is approximately 1000MB, so 4GB is 4000MB.

At 1 MB per minute, you can have 4000 minutes or 66.7 hours of music on a 4GB memory card.
