New Receiver from Denon

de_ avr_s930h_e3_ar_lo.png

The new AVR – Audio Video Receiver – has arrived. Works great.

The choice is the Denon AVR S930H – All the video support and way more Audio support than I need. My speakers are only 5.1 and this one supports 7.2 or as they are saying these days 5.2.2. But I needed this level of support to get HDR10 / Dolby Vision which my TV supports.



An Oppo UDP 203 4K BluRay Player will probably be added in a couple of months to finish the AV system upgrade.


Audacity – Copy / Paste Bug

Audacity has a bug when copy/paste is used on a segment of audio in a track.

Audacity 1.2.6
Vista x86 SP1

To reproduce the problem:

  1. Record a segment of audio.
  2. Select a portion of the audio and
  3. point to a point beyond the audio recording on the same track and
  4. paste. Observe that the pasted audio is tacked to the end of the recording, not at the paste point.
  5. Select the Envelope tool.
  6. Observe that Envelope handles for the pasted audio are displayed beyond the audio data.

I have tried to reproduce this outside of this test project and was not able to reproduce the problem. However, the picture above indicates that this problem does exist for some series of steps.

I suggest that the audio paste should have occurred at the mouse position rather than at the end. This would require adding a segment of silence to the file.

Also, I’m not sure how one can move a segment of audio along a track without moving the entire track. For example, if the alignment of the pasted audio needed to be adjusted, then I’m not sure how this could be done. The Time Shift tool apparently moves the entire track, not just the selection. I’ll check the documentation.

Audio Cooling – How to Stop Fan Hum

For years I’ve had fans in the back of the audio cabinet to keep my stereo stuff cool. Even modern equipment generates a lot of heat, esp the Receiver or any Amps you have.

When I got this audio cabinet about 8 years ago I put 3 fans in it. I got the best fans that I could find to reduce the hum that fans all make – Vantec Stealth 5″, and a Vantec Stealth 3″ for the center bay. There is a small transformer hooked up to the Aux power of the receiver so that the fans turn on whenever the receiver is on.
