|
|
Welcome to Acapobrit Radio.
|
||
|
|
This is Tony Denton, also known as Barryman, with my second podcast.
|
||
|
|
First, my thanks to Poké and Claudio M for their kind comments on my first show.
|
||
|
|
Comments of any kind are appreciated and make podcasting worthwhile.
|
||
|
|
Poké, you should definitely check out jazz music.
|
||
|
|
It's surprising just how wide the scope of it is with something for just about everyone.
|
||
|
|
Claudio M, I do listen regularly to Linux Basements and you and Chad are doing a great job there.
|
||
|
|
Keep up the good work, all of you guys.
|
||
|
|
Among other great podcasts that I regularly listen to,
|
||
|
|
I pack my music's open source musician,
|
||
|
|
and the first podcast I ever listen to deviates is Lotto Linux Links.
|
||
|
|
.
|
||
|
|
In this podcast, I would like to outline how I personally record the show,
|
||
|
|
how I use Linux to record audio in support of my jazz activities,
|
||
|
|
and how Linux supports my workflow generally.
|
||
|
|
First, a bit about my setup and the gear I use.
|
||
|
|
My main microphone is a Berringer USB condenser microphone, C1U,
|
||
|
|
with a boom mic stand and a pop screen.
|
||
|
|
I also have a Sennheiser E815S that can be used as a second microphone
|
||
|
|
with either a Tuscan US100 audio interface or straight into my Zoom H4N recorder
|
||
|
|
to allow multiple inputs.
|
||
|
|
The Sennheiser, by the way, is the microphone that I use for PA in my live performances.
|
||
|
|
The response curve seems to suit solo instruments and saxophones in particular
|
||
|
|
better than other microphones I've tried, with a nice, clear, warm sound.
|
||
|
|
Sure, S58 is a great vocal mic, of course,
|
||
|
|
but since I don't sing, dance or do monologues,
|
||
|
|
I find the Sennheiser a better, slightly cheaper alternative for instrumental work.
|
||
|
|
How the audio is captured depends upon what I'm recording.
|
||
|
|
For example, for recording my voice for this podcast,
|
||
|
|
I'm using the Berringer USB mic straight into the computer,
|
||
|
|
captured in Audacity.
|
||
|
|
Incidentally, I use Klausu's config file to set up Audacity.
|
||
|
|
I find his keyboard controls and screen layout gives me a much faster workflow
|
||
|
|
when I'm editing the podcast.
|
||
|
|
I'll put the link to the config file in the show notes for anyone who's interested.
|
||
|
|
I've also used Arda to record audio, but this is like using a sledgehammer to crack a nut.
|
||
|
|
Arda is great, because he has a steeper learning curve
|
||
|
|
and many, many more features than I required for this particular job.
|
||
|
|
Processing.
|
||
|
|
I use one of two laptops to capture and process the audio.
|
||
|
|
An ACES triply PC, 1.5805H, which has a 10.5 inch screen,
|
||
|
|
and a Sony vio VGN BX297 with a 17 inch screen.
|
||
|
|
Both machines originally came with Windows XP installed,
|
||
|
|
but have since been completely rebuilt with Ubuntu 1010.
|
||
|
|
The ACES is more than up to the job for capturing voice and instrumental recordings.
|
||
|
|
Anything more than that, however, score working is severely, for example,
|
||
|
|
and the size of the ACES screen humps the ability to view a score
|
||
|
|
and to generally move about a score effectively.
|
||
|
|
That is where this Sony comes in.
|
||
|
|
At 17 inches, the screen is ideal for viewing and navigating the musical scores,
|
||
|
|
but more about that later.
|
||
|
|
Initially, in Audacity, I will save the audio file as a wav or flak file
|
||
|
|
to preserve the maximum amount of audio data at that stage of the process.
|
||
|
|
I usually prepare a script for the whole spoken part of the show,
|
||
|
|
and this helps simplify the preparation of the published show notes.
|
||
|
|
I will typically record each segment of the script as a separate file,
|
||
|
|
again in wav or flak format, so that I can easily drop in any audio fills
|
||
|
|
or pieces into the program.
|
||
|
|
I then assemble the segments and the audio in Audacity,
|
||
|
|
adjust the fades and overlaps where necessary,
|
||
|
|
and export and mix down the file to one composite MP3 file.
|
||
|
|
For the HPR podcast, the assembly starts with the supplied HPR intro music
|
||
|
|
and ends with the outro audio.
|
||
|
|
.

||

||
|
|
Music production.
|
||
|
|
Okay, so that's the setup and production of the podcast.
|
||
|
|
What about music writing, arranging and composing?
|
||
|
|
For this purpose, I use either Band-In-A-Box 2009
|
||
|
|
or Subelius 5, depending on my purpose.
|
||
|
|
Now, these two programs are Windows-based and present,
|
||
|
|
and I'm unaware of any suitable Linux equivalent,
|
||
|
|
so I have them loaded in virtual box with Windows XP.
|
||
|
|
Not a particularly satisfactory arrangement for an open source advocate, I grant you.
|
||
|
|
And while I am aware of Muse score, text, fresco-ballty and Rose Garden,
|
||
|
|
none of these are capable of producing the same authentic output as Band-In-A-Box.
|
||
|
|
Band-In-A-Box uses sampled sounds for the backing voices,
|
||
|
|
and so gives a much more realistic sound than a straightforward MIDI patch.
|
||
|
|
Listen to the following backing track.
|
||
|
|
The chord structure here is the Jazz Walls Bluesette.
|
||
|
|
Music production.
|
||
|
|
When I taught Wind Instruments at a local music centre,
|
||
|
|
I used to prepare audio CDs with backing material for students to play along with,
|
||
|
|
like the old Music Minus One thing.
|
||
|
|
We used to give two concerts a year where the students' folks used to come and listen,
|
||
|
|
so there was always a need for performance material, as well as the technical stuff.
|
||
|
|
Well, Band-In-A-Box is ideal for preparing backing tracks for this type of material.
|
||
|
|
Having selected a suitable piece for the performance, I entered the chord structure into the program,
|
||
|
|
and set the number of choruses for the performance.
|
||
|
|
Next, the type or style of backing is selected, which sets the appropriate voicing for each track.
|
||
|
|
Now Band-In-A-Box has a facility for outputting audio as a WAV or MP3 file,
|
||
|
|
also with the ability to burn the file to a CD.
|
||
|
|
The next part of the process is to prepare the written music for the various parts for students or players.
|
||
|
|
This is done in Sibelius.
|
||
|
|
It is possible to import tracks from Band-In-A-Box right into Sibelius,
|
||
|
|
and I might use the piano part for this purpose.
|
||
|
|
Then the melody in various harmony parts can be written over on the top of this part,
|
||
|
|
and the whole thing checked against the audio playback before printing out to a separate part.
|
||
|
|
This method gives me the flexibility to tailor each part to the ability of the individual student,
|
||
|
|
and I've seen me write a part for an absolute beginner based on just two or three long notes behind the rest of the ensemble.
|
||
|
|
Sibelius is great for writing the technical exercise stuff as well.
|
||
|
|
I just wish there was some equivalent software in Linux to do this kind of thing.
|
||
|
|
I would move there in a flash if I could find some.
|
||
|
|
Other activities.
|
||
|
|
The need to use multiple machines can give problems with maintaining the integrity of the work in progress,
|
||
|
|
keeping files up to date, ensuring the use of the correct version, and so on.
|
||
|
|
Well, I get over this problem through the use of Dropbox.
|
||
|
|
I keep the files that I'm currently working on in a folder or series of folders on Dropbox.
|
||
|
|
Thus, whenever I pick up a different machine, say either of my laptops or the desktop,
|
||
|
|
I can be sure that I'm working on the very latest version.
|
||
|
|
Of course, when the particular project is complete, I move the folders from Dropbox onto my large one terabyte external drive for archive storage.
|
||
|
|
I begin to get the hang of this now.
|
||
|
|
And in my next podcast, I'll explain how I use Linux software in the production of my websites and how I use it for more general purposes.
