Bought the book last week but the little pocket which attached the disc to the back cover was incorrectly manufactured, leading the data side of the disc to be covered in glue and scratches… any way I can download the disc contents from somewhere?

Listing 2.5.11 page 279

Book currently reads:
if(stream->npoints < 2)

But it should read:
if (npoints < 2)

So I found a great post that helped.:
http://bhou.wordpress.com/2011/09/13/how-to-install-gnuplot-in-mac-os-x-lion/

He explains how to install gnuplot for osx lion. Also the second comment has a link to a program called homebrew that makes installing gnuplot a breeze!

I just got to the part in chapter 1 that uses gnuplot. The DVD comes with a pre packaged gnuplot-4.0. After installing it I went into the terminal and tried to run it but got an error: “Launch of “gnuplot” failed: the PowerPC architecture is no longer supported.” I was able to track down the [...]

Hello, I’m currently learning C at school, so I bought a copy of The Audio Programming Book for personal study. While doing the exercises in chapter 0, I found a small bug in the function-based interval program. When the user enters 2 wrong notes, the program returns a unison instead of reporting the error. While [...]

Victor Lazzarini suggested to me that the following would work to fix the problem…

… just replace the check for wrong notes by this:

if(nameToPc(note2) == 100 || nameToPc(note1) == 100)
AlexAB · 5 months, 2 weeks ago
Hello, and thanks for your reply.
In fact, this is more or less what I came up with, I then added another if()…else if() condition to have the program return the exact wrong note in the case where the user would enter one good note and one bad note.
The code is on my laptop so I don’t have access to it right now but it was something like:

if(nameToPc(note1) == 100 && nameToPc(note2) == 100)
printf(”neither %d nor %d are natural notes”, note1, note2);
else if (nameToPc(note1) == 100)
printf(”%d is not a natural note”, note1);
else if (nameToPc(note2) == 100)
printf(”%d is not a natural note”, note2);

I just didn’t want to post it right away in case other beginners like me would wish to solve it themselves ..

Thanks again!

Alex

Hi all, I’ve been trying to get the DFT (chapter7) example going in Visual Studio C++ (sorry), and I get an Access Denied on the command line. Also dft.exe is not a valid Win32 program. I’ve tried config of both 32 bit & 64 bit to no avail. I’m trying to statically link to libsndfile [...]

In Chapter 1, tables 1.2 and 1.3 (referred to in the text on pages 117 and 107 respectively) seem to be missing altogether.

Roberto Garreton posted on the forum topic Erratum in the group The Audio Programming Book: 9 months, 1 week ago · View

got what was the problem.
Chapter one, on the book and on the file in the DVD, Listing 1.9.4 says on line 36:
angleincr = twopi*freq/nsamps;
and should say:
angleincr = twopi*freq/srate;The same mistake happens on listing 1.9.5

Roberto Garreton posted on the forum topic Erratum in the group The Audio Programming Book: 9 months, 1 week ago · View

On the first chapter, the program tfork2 (listing 1.9.4) gives me a different pitch. After checking character by character, I couldn’t find any typo. Then I run the program from the CD and the same. Giving a frequency of 440, sr 44100, 1 channel and amp 1, the resulting frequency is 88hz. The tfork program (listing 1.9.3) gives [...]

Hi guys,
I tried the solution here, but I couldn’t find any single comment line…
I just cant compile the thing!
Anyone had (another) tip or just have a compiled executable to use?
Thanks,
Roberto

It is working already… don’t know how and why though.

is this the right place to suggest errata? I’m not far into the book, but suggest these.. 0.9.2 – ‘multiplication’ should read ‘division’ 0.12.24. pointer declarations; return-type (*pointer-name) (arguments); [ <- no square bracket at the end. 0.13 ...is a valid assignment to an int, and... strcpy(note.name, "C" ); should read strcpy( firstnote.name, "C" ); [...]

Dear Readers of The Audio Programming Book. Thanks so much for the code and information and opinions that you have shared here. Your reports of these errata are especially important to us. MIT Press contacted me today and asked for a complete list of typos and erratum so that they could correct these for the [...]
