File and Folder Structure

The folder name and file name can be displayed as the title during MP3 play. However, the title must be within 31 and 27 single-byte alphabetical letters and numerals for the folder name and file name, respectively (not including an extension). Entering more letters or numerals than specified may cause an incorrect display. A disc with a folder having more than 8 hierarchical levels will conflict with MP3 system requirements and playback will be impossible.

A total of 255 filers and folders are allowed. When the number of and folders is more than 255, playback of tracks in excess of that number is impossible. There is a maximum of 31 files in each folder. File tracks are played in the order that they were recorded onto a disc. (Files might not always be played in the order displayed on the PC.)

Sound Quality

Some noise might be audible - this depends on the type of encoder software used while recording. It is not noise created by the OHMD74.

Bit Rates

The OHMD74 supports the following bit rates: 32kHz, 44.1kHz, 48kHz, and 96kHz. In case of a track recorded at VBR (variable bit rate), the display for the play time of the track may be slightly different from the actual playtime. Also, the recommended value for VBR ranges from 32 kbps to 320 kbps.

ID3V1 and ID3V2 Tags Support

Both ID3V1 and ID3V2 tags are supported. These allow up to 30 characters per song name and 30 characters per artist name.
