5 Sound Access is a program for viewing and analysing the contents
|
|
lbajardsilogic@43
|
6 of a multimedia archive.
|

|
|
lbajardsilogic@43
|
8 With Sound Access you can:
|
|
lbajardsilogic@0
|
9
|
|
lbajardsilogic@43
|
10 * Query a multimedia archive on audio caracteristics (author,
|
|
lbajardsilogic@43
|
11 title, tonality, audio content...)
|
|
lbajardsilogic@0
|
12
|
|
lbajardsilogic@43
|
13 * Load and visualize audio files, related metadata and related media
|
|
lbajardsilogic@43
|
14
|
|
lbajardsilogic@43
|
15 * Add your own annotation metadata to an audio file of the archive
|
|
lbajardsilogic@43
|
16 and export it in an external file
|
|
lbajardsilogic@0
|
17
|
|
lbajardsilogic@43
|
18 * Run feature-extraction plugins to calculate metadata
|
|
lbajardsilogic@43
|
19 automatically, using algorithms such as beat trackers, pitch
|
|
lbajardsilogic@43
|
20 detectors and so on
|
|
lbajardsilogic@0
|
21
|
|
lbajardsilogic@43
|
22 * Run realtime audio plugin in cascade for source modification (source
|
|
lbajardsilogic@43
|
23 segmentation, noise reduction, pitch/scale modification...)
|
|
lbajardsilogic@0
|
24
|
|
lbajardsilogic@43
|
25 * Play back the original audio with related metadata and
|
|
lbajardsilogic@43
|
26 related media, taking care to synchronise playback with the
|
|
lbajardsilogic@43
|
27 display position
|
|
lbajardsilogic@0
|
28
|
|
lbajardsilogic@43
|
29 * Slow down playback and loop segments of interest, including
|
|
lbajardsilogic@43
|
30 seamless looping of complex non-contiguous areas
|
|
lbajardsilogic@0
|
31
|
|
lbajardsilogic@43
|
32 Sound Access can also be controlled remotely using the Open Sound
|
|
lbajardsilogic@0
|
33 Control (OSC) protocol.

|
39 First, please consider getting one of the ready-to-run binary
|
|
lbajardsilogic@43
|
40 distributions available from http://sourceforge.net/projects/easaier/.
|
|
lbajardsilogic@0
|
41
|
|
lbajardsilogic@0
|
42 The following additional libraries are required or optional when
|
|
lbajardsilogic@43
|
43 building Sound Access:
|
|
lbajardsilogic@0
|
44
|
|
lbajardsilogic@0
|
45 REQUIRED Vamp Plugin SDK http://www.sonicvisualiser.org/
|
|
lbajardsilogic@0
|
46
|
|
lbajardsilogic@0
|
47 REQUIRED Qt4 Free Edition http://www.trolltech.com/
|
|
lbajardsilogic@0
|
48 REQUIRED libsndfile http://www.mega-nerd.com/libsndfile/
|
|
lbajardsilogic@0
|
49 REQUIRED libsamplerate http://www.mega-nerd.com/SRC/
|
|
lbajardsilogic@0
|
50 REQUIRED FFTW3 http://www.fftw.org/
|
|
lbajardsilogic@0
|
51 REQUIRED bzip2 library http://www.bzip.org/
|
|
lbajardsilogic@0
|
52
|
|
lbajardsilogic@0
|
53 Optional JACK http://www.jackaudio.org/
|
|
lbajardsilogic@0
|
54 Optional PortAudio v18 or v19 http://www.portaudio.com/
|
|
lbajardsilogic@0
|
55 Optional MAD mp3 decoder http://www.underbit.com/products/mad/
|
|
lbajardsilogic@43
|
56 Optional Oggz and fishsound http://www.xiph.org/downloads/
|
|
lbajardsilogic@43
|
57 Optional liblo OSC library http://www.plugin.org.uk/liblo/
|
|
lbajardsilogic@0
|
58
|
|
lbajardsilogic@0
|
59 Although JACK and PortAudio are individually optional, you will need
|
|
lbajardsilogic@0
|
60 to have one or the other of them in order to get any audio playback.
|
|
lbajardsilogic@0
|
61 Usually JACK is preferred on Linux and PortAudio elsewhere.
|
|
lbajardsilogic@0
|
62
|
|
lbajardsilogic@0
|
63 If you happen to be using a Debian-based Linux, you probably want to
|
|
lbajardsilogic@0
|
64 apt-get install the following packages: libqt4-dev libsndfile1-dev
|
|
lbajardsilogic@0
|
65 libsamplerate0-dev fftw3-dev libbz2-dev libjack0.100.0-dev libmad0-dev
|
|
lbajardsilogic@0
|
66 liboggz1-dev libfishsound1-dev liblo0-dev.
|
|
lbajardsilogic@0
|
67
|
|
lbajardsilogic@0
|
68 If you are building on a Unix-like system that supports pkg-config and
|
|
lbajardsilogic@0
|
69 uses it for all appropriate libraries (such as a modern Linux
|
|
lbajardsilogic@0
|
70 distribution) then you should be able to just run "qmake" (being
|
|
lbajardsilogic@0
|
71 careful to ensure it is the Qt 4 version of qmake you are running, and
|
|
lbajardsilogic@0
|
72 not a Qt 3 version).
|
|
lbajardsilogic@0
|
73
|
|
lbajardsilogic@0
|
74 If you do not have pkg-config, you should first edit the file sv.prf
|
|
lbajardsilogic@0
|
75 and comment out any of the optional HAVE_* lines (in the section
|
|
lbajardsilogic@0
|
76 starting "If you don't have pkg-config...") for library dependencies
|
|
lbajardsilogic@0
|
77 that you aren't using. Then run the Qt 4 "qmake" command. This will
|
|
lbajardsilogic@0
|
78 create the proper Makefile.
|
|
lbajardsilogic@0
|
79
|
|
lbajardsilogic@0
|
80 (If you're on the Mac and you have Qt3 installed as well, you must
|
|
lbajardsilogic@0
|
81 export QMAKESPEC=macx-g++ before you do this, or Qt will get confused.)
|
|
lbajardsilogic@0
|
82
|
|
lbajardsilogic@0
|
83 Then type "make". The program will then either build, or not build.
|

84
|
|
lbajardsilogic@43
|
85 Under Windows, the VC project is provided. You can used it to
|
|
lbajardsilogic@43
|
86 compile the sources with Visual Studio 2005 Pro or Visual Studio Express 2005.
|
|
lbajardsilogic@43
|
87 Note that in this case Qt must also be compiled with Visual Studio
|
|
lbajardsilogic@43
|
88 (http://qtnode.net/wiki/Qt4_with_Visual_Studio).

92 -------------------------------

93
|
|
lbajardsilogic@43
|
94 Sound Access requires Qt version 4.x. It can not be built with
|
|
lbajardsilogic@0
|
95 Qt 3 or earlier.
|
|
lbajardsilogic@0
|
96
|
|
lbajardsilogic@43
|
97 You can build Sound Access using Qt 4.0, 4.1, or 4.2, but the
|
|
lbajardsilogic@0
|
98 build scripts provided will only work with Qt 4.2 because of an
|
|
lbajardsilogic@0
|
99 incompatible change in the Qt build utilities. Please read
|
|
lbajardsilogic@0
|
100 README.Qt41 if you want to build with Qt 4.0 or 4.1.
