procedure for Mandir live broadcast

Documenting the Mandir live broadcast procedure.

1. Power on procedure is:
   (a) UPS input on
   (b) UPS on
   (c) Extension box power on (right-hand side of equipment box)
   (d) Tascam US-1641 power on
   (e) MacBook power on
   Power down procedure follows in the reverse order.
2. In the MacBook, the programs to be run are in right-to-left order in the Dock. We start by powering up the Tascam Control Panel app.

3. In the Tascam Control Panel, choose the dropdown to change the Digital output channels from line out 1 & 2 to line out 3 & 4.

4. Next, fire up the Jack Pilot app.

5. Press the start button in Jack Pilot to start Jack. Wait till Jack starts up, with a wait dialog box indicating the starting of Jack.

6. Next, start the BUTT app.

7. And finally start Reaper.

8. Now set up routing in Jack for broadcast. For this, click on the Routing button in Jack Pilot, and choose File -> Load Studio Setup, choosing the broadcast_setup.jks file.

9. The setup can be tested by playing the output of reaper. Reaper channels 1-8 are mapped to sliders 1-8 on the Korg NanoKontrol. Channels 9-14 are mapped to knobs 1-6.
   
   Channel 12 (knob 4) has instrumental music and
   Channel 13 (knob 5) has the pre-live announcement pre-loaded.
   Channel 14 (knob 6) has the full mix output of PA mixer coming in.
   Pressing play on the Korg NanoKontrol allows you to test whether the BUTT gets signal when knob 5 is opened, as seen by the lit up LED-style indicators on BUTT.
10. Start playback of pre-live Announcement in Reaper approximately 3 minutes before desired start of live broadcast.
11. Press the 'Play' button in BUTT to start live broadcast on AsiaStream.
12. 
    Double-click the "startlive.command" shortcut on the Desktop to start live broadcast on TeluguStream.
13. 
    
    
    Fade out knob 5 and allow knob 6 to maintain around -12 dB at the output when the program starts. Playback can be stopped with the stop button on the NanoKontrol.
14. Recording of programs is mapped to Channel 15 which is record enabled. The spacebar is the shortcut key.
15. If recording is in progress, if a filler instrumental is to be added, BI.mp3 can be dragged from desktop to Channel 12 (knob 4) which has record enable DISABLED - the dull red ar button.
    Unless the track has record enable Disabled, playback will not occur from the track.
16. 
    The same procedure as above can be used to drag and drop the ANN_END_LIVE end announcement file for playout at the end if no one is available for live announcement.
17. The microphone with stand available can be connected to the XLR input Channel 8 on the Tascam, and this can be used for Live announcements.
18. In case there is live video streaming, the network cable tagged "Studio" has to be disconnected from the Macbook and connected to one of the BLUE coloured LAN ports of the router. The router has to be plugged into the UPS. The lan cable from the router has to be plugged into the MacBook. This setup has to be restored at the end of the live broadcast by unplugging the router and restoring the "Studio" tagged network cable, connecting it back to the Macbook.

Yamaha audiogram and "noise in recording"

I got a call from SK saying they are trying to start work at the newly inaugurated Studio, with a Yamaha Audiogram 6, but the recordings turn out to have some noise. My reply:

Some of the probable reasons are given in the forum posts below:
http://forum.recordingreview.com/f23/yamaha-audiogram-6-cubase-ai4-18362/

1. Upgrade to Windows XP SP3
2. Make sure you have connected to a USB2 port and not to USB1
3. Make sure no other device (like mouse) are connected to the same bus (using device manager, you can check this.)
   
4. Increase the buffer as given in the forum posts above

save a particular web page at predefined intervals in a specific folder

NA had this query - how to automate saving  a particular  web page ( Specified  url in the settings )  at  predefined intervals  in a specific folder.

My reply:

I assume you want to do this on a Windows machine. On a Linux machine this is quite easy.

For Windows:

write a vscript file to save the webpage as given in
http://www.computerhope.com/forum/index.php?topic=110781.0

Schedule it to run periodically using Windows task scheduler as given at
http://www.iopus.com/guides/winscheduler.htm

Follow-up about making the filename unique for each grab:
filename changing can be managed by massaging the vbs file, appending the date-time to the filename or something like that. Since I'm not a vbs guru, I'm not spending time on it to modify the file for you. :)

Also, making Windows Scheduled tasks repeat tasks every few minutes:

NA reported that he has successfully implemented this.

Laptop DVD drive troubleshooting

Guest post from DJ:

Platform: 

Dell Vostro 1400

Windows XP SP3

Problem: For over a year the CD/DVD RW player did not perform properly. Jittery playback of Audio CD and most commercial DVD discs were not read. Writing was producing errors and most DVD R blanks were not recognized. 

Analysis 1: Drive lens problem. Cleaned it a couple of times - No positive impact

Analysis 2: Drive hardware problem. - Result out of laziness did not bother to fix and planned to buy external USB drive.

Analysis 3: (After over an year of sadness and lack of enthusiasm). Lens and hardware at fault. 

Took out my camera lens cleaner kit and carefully cleaned the lens. Still there was jitter. But all discs and DVD's were recognized. This gave me hope. Also I noticed that during DVD playback the computer response was sluggish. This prompted to think of DMA. In Device manager I found that the mode was sett to PIO and DMA was not an option. This was quite strange. Out of curiosity I checked the Dell website for any available updates. 

There was a firmware update available for the DVD drive. Carried out firmware upgrade for the DVD drive. Voila - Now it works like a charm. All DVD's are playing smoothly. Have not yet tried burning any discs yet.

I still cannot figure out how the firmware got corrupted - the DVD drive used to work fine earlier!

order mixup on schedule page

Our schedule page appeared to have some sort of bug where the order of some files would get mixed up in the "Listen Now" or downloads listings. The reason seemed to be that the files were being shown in the order of the playlist based on timestamp, but the timestamp only had hours and minutes, and not seconds, in the csv file generated from our local database and uploaded to the server. So, those files which had durations of less than a minute would have the same timestamp as the next file, and these two files would be interchanged during the display. So, today, added seconds to the csv, and the bug seems to have gone away. B tested the import before and after, etc.

bug-fixing the downloads links in search results

After the javascript for sorting the table was added to the audio search results page, there was a bug introduced, brought to our notice by a listener. Due to the way in which the javascript call was written, sorting the table caused the wrong links to appear. B, who had written the original code, fixed it by changing the javascript calls to explicitly reference the fids.
