I have just downloaded Voxengo and have now got it into Audacity by copying Voxengo's 32bit SPAN.dll file into Audacity's Plug-in folder. When Audacity is loaded, and a file imported, the bottom of the 'Effect' drop-down menu shows 'Voxengo:SPAN'. If you press this, the Voxengo screen appears. That's as far as I've got, I am now stuck. I do not know how to get a waveform into it.
I've got to learn about Voxengo......looks like a bit of a mountain to climb. Can anyone get me to the next stage at all?
Hi Roger, When you play the track that the plugin is placed in, the response curves should immediately appear on the graph. One shows the peaks (the higher one), and the other the instant or average responses depending on the settings made. There are settings that can be made in the plugin. At the lower right there is Peak Hold. I always set that to Inf (infinity). At the top left I usually leave Block at 2048 (setting it higher can reveal a more complex and accurate response but for most purposes it can become too revealing, if that makes sense, which could drive you crazy with trying to correct every little detail, this is where you have to learn which details to take note of and which can be ignored. For example, you might have a recording that has a prodominant single note throughout the tune, therefore it stands to reason that this predominant note will tend to show as a peak in the response at its frequency. The trick is to make sure that the other tracks' responses fill in the space either side of that single note). Slope should be set to 0dB to see the wave as it actually is, but setting it to tilt at 6dB can show the sloping response above 500Hz as a level one instead so as to make it easier to see if it has the required slope or not, and this can be changed while the track is playing to see the response up to 500Hz (set at 0dB slope) or the response above 500Hz (set at 6dB slope). I usually leave the Channel setting at Avg (average). The Monitor setting I change to Avg (average), the other two settings Instant and Full I leave as they are. With the settings I normally use, the wave will gradually change shape as the track plays, and after the whole track has played it will show the average response of that track. Sonar 2, which I use, has a master output section and I usually put the plugin there so that I can test an individual track by muting the others, or play them all to get an idea of the whole mix response. Used in the latter way it will also help you to decide whether an instrument or other sound is too loud in the mix (by running the test with and without that instrument or sound) or to see whether its EQ needs some attention to make it fit in the mix better. Remember that the plugin does nothing except to show you what the recording's response looks like and to enable you to make EQ and mixing balance decisions. If the plugin is placed in an individual track, it will only show the results of plugin effects that are placed before it, so the plugin should always be the last one in the plugins order in the track eg. EQ, compressor, Voxengo Span, in that order, to see what effect the EQ and compression has. However, I have found that compressing a track usually makes little difference to the frequency response but it is still better to make sure that Voxengo Span is monitoring everything that is effecting the track (or whole mix). One final hint, do not rely on it to decide the actual level of a track, that is still best done by the recording program's own level indicators. Regards, Charlie
Thank you for the valuable information. I'm still struggling at the starting blocks I'm afraid. When I load Audacity, the 'Effects' drop-down menu items (of which Voxego SPAN is the bottom entry), are greyed out. However, when I load a file, the 'Effects' menu lights up, and the items are selectable. If I press the Voxengo SPAN button, the Voxengo screen appears, but there is no waveform on it. It's almost as if it's waiting for a waveform. If I press the ok button on it, the Voxengo screen disappears and a box with a loading bar appears and completes a load. Following the load, it puts two yellow boundary lines along the top and bottom of the Audacity waveform. I cannot make any sense of this. I am now stuck...
Hi Roger, I don't really understand what is happening and I don't know Audacity, perhaps someone could show how to correctly place plugins in Audacity's individual tracks and/or the final mix section? The fact that it does at least show up is encouraging. Were you not able to get as far as playing the track to be monitored by Voxengo Span? Nothing should show in its graph until track play and the first sound (or noise) begins. Regards, Charlie
I can't play the track with the Voxengo screen displayed, as the 'play' button is on the Audacity screen. All it does, is gives me an audiable 'ding' to say that I am on the wrong screen. I can only press the play button if I cancel the Voxengo screen. If I press the 'preview' button on the bottom left of the Voxengo screen, it plays a couple of seconds or so of my track and also shows a quick waveform on it's screen, but then they both finish. I cannot find anywhere else to put the SPAN.dll except into the plug-in folder (which Voxengo recommends). I have tried installing it into Nero Waveditor, but although installed, the program doesn't appear to see it. I will carry on fiddling.
Hi Roger, In Sonar 2, there are two ways to use plugins. One is to highlight the track you want the effect in, then select the plugin from the Process menu at the top of the screen, then Audio Effects, then the required plugin from the drop down list. This enables you to audition the plugin for a couple of seconds, then if you are happy you can process the track. this is no use for using Voxengo Span and I think is more or less what is happening in your case. In fact, I just tried it that way and I got an error message saying that Voxengo was incompatible with Sonar and would I like to remove it! The other way is to right click on the effects section in the track itself, then select the plugin from the list. This places the plugin into the actual track. This is what you need to do, or the equivalent of it, if that is possible in Audacity. Regards, Charlie
Hi Roger and Charlie, Unfortunately Audacity can not do effects in real time and so something like Span isn't suitable ... as you have discovered !!
I use Audacity for recording, editing, etc then export the tracks as 32 bit FP Wav and load them into Reaper (uncrippled version is free to try for as long as you wish) for final mixdown, mastering etc. Span works well in Reaper and it also has it's own equivalent that can be used to do EQ adjustments whilst listening and watching in real time. It is an excellent program with updates and enhancements every week or so ... but fairly complicated which is why I continue to use Audacity.
Just to let you know that I have just purchased Sonar Home Edition 7 (now the fun starts). I have just installed the VoxengoSPAN plug-in. The VoxengoSPAN screen is now displayed when selected from the effects menu. I can also run the music file with waveform detail appearing live on the VoxengoSPAN screen. Doesn't mean anything to me yet, but so far so good. Very early days. Now I start climbing the mountain.....
Hi Roger, Well done for buying Sonar, I'm sure you'll be pleased with it. I run mine in 24 bit mode for better editing, then export a finished track as 16 bit. There are hundreds of free plugins to be had, some are really good too. The best part now is that you will be able to hear a whole single track with a plugin applied and make the settings you want before processing the track. Regards, Charlie
Thanks for that. I'm afraid that I come from the bygone era of using analogue oscilloscopes to look at radios/t/v's/amplifiers/tonal networks etc. Although in recent years prior up to my retirement I was using digital 'scopes in my job (electronic test equipment design). I think it's a matter of finding my way around the programs. It could be a looooooong road. Still, the learning starts here.
