FAQ and troubleshooting
How much music will my Rio hold?
The amount of music you can store in your player or on your computer depends on the
amount of memory you have available. The following table shows the amount of memory
required to store one minute of stereo music for the given bitrate.
How to calculate play time
Note: Due to different software compression algorithms, the following information
may vary slightly depending on what software you are using and what program the
MP3 was created by.
To determine how much play time your Rio actually has, use the following equation:
Rio Play Time = M / (S x 0.439) where:
M = Rio memory size in MB (32MB, 64MB, 128MB, and so on).
S = Sampling Speed in kbps (128kbps, 80kbps, and so on).
The higher quality the MP3, the larger its size, causing it to take up more room in your Rio’s
memory.
The following bitrates are supported:
•
256 kbps, CD Quality, 5.6:1 reduction.
•
192 kbps, CD Quality, 7.5:1 reduction.
•
160 kbps, CD Quality, 9:1 reduction.
•
128 kbps, CD Quality, 11.25:1 reduction.
•
96 kbps, Near CD, 15:1 reduction.
•
80 kbps, Near CD, 18:1 reduction.
•
64 kbps, FM Radio, 22.5:1 reduction.
What are the differences between MP3 and WMA?
If you use the WMA format instead of the MP3 format, you can have comparable quality at
about one half the size. Since WMA offers “CD quality” at a smaller file size than MP3, it
enables you to store more music on your PC or on your portable player. WMA files are exclu-
sive to the PC.
