Minimizing distortion in a digital board

The best way to minimize distortion in a digital board is to control the input. I’ve been using the Aphex 207D on vocal mics for a while now and love the MicLim circuitry that keeps the channel from distorting.

Here I’m running the vocals through a Heil PR35 capsule on a Shure SLX wireless system.  The output of the wireless Rx runs in to the 207D, which converts the signal to digital and runs in to my board through the AES inputs.

 

Recommended Free VST Plugins

I’ve been doing some mixing lately again and have been looking for some good free VST plugins.

I’ve come across this compressor, the D2, that seems to work really well and sounds decent so far with what I’ve thrown at it.

I’ve also liked this reverb plugin, the epicVerb.  It has some really nice sounds and is pretty easy to tweak and adjust to the sound the you want.

I also came across a guy who is putting out free virtual instruments, DSKmusic.com.  If you are doing any composing with midi and are looking for some free instruments or synth/sound generators, this guy has a bunch of free stuff.  I particularly like the Virtuoso and Ethereal PadZ2.

I’ve also been able to get some nice warm EQ sound out of the BootEQ MkII plugin.  The EQ isn’t harsh and sounds very natural.

All good stuff for the price, FREE.  Thanks guys for making these plugins available.

Replace Drum Track With Midi Trigger Using Reaper and Grizzly

I figured out how to do something fun and useful that I thought I’d share.  I wanted to replace a recorded drum track – in this case the kick drum, from a live recording with a sampled kick drum sound.  I used Reaper as the multi-track DAW ($60 for non-profit) and Grizzly (Free) as the Drum Virtual Instrument.  For the sake of this tutorial I’ll assume that you have both installed properly.

1. Initial Track Setup

This isn’t really a step, but it just shows you the initial track arrangement in Reaper.  Notice the kick drum track that we will be working with.

2. Insert Drum Trigger

First we will insert the drum trigger effect in to the kick drum track.  This is the effect that will use the recorded audio to generate a midi trigger signal.  Do this by clicking the “Track Insert FX” area that is the top most part of the track in the mixer view.  Search in the FX dialog for “trigger” and you should see the SStillwell/drumtrigger effect.   Select it and click ok.

3. Insert Grizzly Virtual Instrument

Go to the Insert menu in Reaper and select “Virtual Instrument on new track…”  Search in the dialog for “Grizzly” and you should see the Grizzly Virtual Instrument.  Select it and click ok.

4. Select NO to build routing prompt

You will receive this prompt, but since we are only replacing one track, the kick drum, and don’t need individual tracks for any other sounds, just the default stereo track will be fine.  Click NO.

5. Set the Midi Note

Look at the midi note assigned to Pad 1 in Grizzly.  The default is 36.  Enter this note in to the SStillwell/drumtrigger effect in the midi note parameter.  Here the midi note has been set to 36 in the drum trigger.

Note that in the top pull down of Grizzly you can select different drum kits to obtain a kick drum sound you like.  Click the Play button of Pad 1 to hear the sample.  You can also define your own sample by clicking the folder icon in Pad 1.  I also turn the volume all the way up to 100.

6. Add  track send to kick drum track.

So now we need to create the link between the kick drum track and the Grizzly track.  So, click the “Track Sends” area of the track, which is right below the “Track Insert FX” area.  You will be presented with the following dialog.

Use the “Add New Send” drop down to select the Grizzly track, your setup should now look like this.

7. Adjust the trigger threshold

You should now be able to playback your project and the audio from the original kick drum will now be triggering the sample in Grizzly.  Adjust the Open threshold so that each kick sound causes Grizzly to be triggered, and the close threshold so that background noise doesn’t trigger any sound.

Thats it, you’ve now replaced the live recorded audio with a sample.

Live streaming audio for free

spkrStreaming live audio of your worship service can be a great service to people who can’t physically make it to church on Sunday.  Missionaries, shut-ins or even members who have to stay home with sick kids.

Here are 3 simple steps to free audio streaming at your church.

1. Audio source
You need a way to feed audio in to a computer that is internet connected.  You could probably use the built in sound card, but I’d recommend using an external USB audio device for better sound quality.  You may already have these kinds of things laying around your church.

2. Encoding Software
You need to download the free Windows Media Encoder.   This program will take your source audio and encode it to an mp3 stream that can be sent to a streaming server.

3. Streaming Server
You need a streaming server for people to connect to and listen to your audio.  You can obtain this service, free for churches, from www.netbroadcasting.tv.  By sending them an email with your church website, they will setup an account for you.  Its quick and easy and once your account is setup, they will send you an email with simple step by step instructions on how to configure Windows Media Encoder, and also how to get the streaming content placed on your church website.

Thats it!  Happy streaming.
