MIRAN - Change the Music 2
First, obtain some nice, royalty-free, music (more difficult than you might think!). Convert it. Then copy it to the Miran, and select it.
Files must be mono, 8Khz, RAW (headerless) A-law (.ALW) or μ-law (.ULW) depending on the Miran. Filenames must be 8.3 format.
Open Audacity, and open the music file: File Open
First thing to do is to convert it to mono: Tracks Stereo Track to Mono
Next, re-sample at 8Khz: Tracks Resample...
Enter 8000, and click OK
Export the audio: File Export Audio...
In the Save: Export Audio window, select the following:
- File type: Other uncompressed files,
- Header: RAW (header-less), and
- Encoding: U-Law (depends on Miran)
Ignore the warning (which only appears if you specify a ULW file extension), and click Yes to save.
Copy the .ULW file(s) to a compact flash card, and place the card in the Miran card face plate (drive A:).
Log into the Miran Card, via serial or telnet.
It's not a good idea to play music from the A: drive. If the flash card is removed, you'll lose your hold-music.
From the main menu, choose: 2. Pack Administration 1. File Commands
Move (or copy) files to the internal drive C: as required.
From the main menu, choose: 1. MIRAN Administration 1. Announcement Configuration 1. Calendar Operations
To play the music, it must be assigned to a channel and calendar. The channel is always 0 for hold music.
Choose: 2. Calendar Assignment
- Enter 0 for the channel (hold music)
- Select the desired filename (ideally copied on drive C:)
- Enter * in the date and time fields to indicate 24/7.
- Select Add to Calendar, and press enter.
Dial the hold music access code (ACOD) and confirm the new music source is heard.
End of procedure!
