How many minutes of MP3 music can be stored in the Joybee 150 Digital Audio Player?

It depends on the memory capacity of the player and the compression ratio used in encoding the MP3 files. For MP3 files encoded by MPEG1 Layer3 with a bitrate of 128kbps and sampling frequency of 44kHz (most commonly used), 1MB of memory can store about 1 minute of music. i.e. 128MB/256MB of memory stores about 128/256 minutes of music.

How long is the maximum recording time?

Recording time depends on the encoding method, bitrate, sampling frequency and memory capacity of the player. If high sound quality is not needed for recording of meeting or lecture, lower bitrate and sampling frequency such as MPEG1 Layer3, bitrate: 16kbps, sampling frequency: 16kHz are recommended. To record with high sound quality, use higher bitrate and sampling frequency such as MPEG1 Layer3, bitrate: 224kbps, sampling frequency: 48kHz. The following table shows the recording time for different settings of

recording. Please see "Record Setup" on page 14 for how to configure them.
