Most people seeking very-near-CD-quality audio encode at a quality of 5 or, for lossless stereo coupling, 6. The default setting is quality 3, which at approximately 110kbps gives a smaller filesize and significantly better fidelity than .mp3 compression at 128kbps. <p><em>This explanation was copied from

When uncompressed u-law has roughly the precision of 14-bit PCM audio and A-law has roughly the precision of 13-bit PCM audio. A-law and u-law data is sometimes encoded using a reversed bit-ordering (i.e. MSB becomes LSB).<br> <b>ADPCM </b> is a form of sound compression that has a good compromise between good sound quality and fast encoding/decoding time. It is used for telephone sound compression and places where full fidelity is not as important. When uncompressed it has roughly the precision of 16-bit PCM audio. Popular versions of ADPCM include G.726, MS ADPCM, and IMA ADPCM. It has different meanings in different file handlers. In .wav files it represents MS ADPCM files, in all others it means G.726 ADPCM. <br> <b>IMA ADPCM</b> is a specific form of ADPCM compression, slightly simpler and slightly lower fidelity than Microsoft's flavor of ADPCM. IMA ADPCM is also called DVI ADPCM.<br> <b>GSM</b> is a standard used for telephone sound compression in European countries and is gaining popularity because of its good quality. It is usually CPU intensive to work with GSM audio data.</p> <p><em>Description based on the SoX manpage</em></p></string> + </property> + </widget> + <widget class="QLineEdit" row="1" column="1"> + <property name="name"> + <cstring>m_editSamplerate</cstring> + </property> + <property name="enabled"> + <bool>false</bool> + </property> + <property name="text"> + <string>14400</string> + </property> + <property name="whatsThis" stdset="0"> + <string></string> + </property> + </widget> + <widget class="QLabel" row="3" column="0"> + <property name="name"> + <cstring>textLabel4</cstring> + </property> + <property name="text"> + <string>Data size:</string> + </property> + </widget> + <widget class="QLabel" row="2" column="0"> + <property name="name"> + <cstring>textLabel3</cstring> + </property> + <property name="text"> + <string>Data encoding:</string> + </property> + </widget> + <widget class="QLabel" row="0" column="0"> + <property name="name"> + <cstring>textLabel1</cstring> + </property> + <property name="text"> + <string>Channels:</string> + </property> + </widget> + <widget class="QComboBox" row="0" column="1"> + <item> + <property name="text"> + <string>1 (mono)</string> + </property> + </item> + <item> + <property name="text"> + <string>2 (stereo)</string> + </property> + </item> + <item> + <property name="text"> + <string>4 (quad sound)</string> + </property> + </item> + <property name="name"> + <cstring>m_comboChannels</cstring> + </property> + <property name="enabled"> + <bool>false</bool> + </property> + </widget> + <widget class="QComboBox" row="3" column="1"> + <item> + <property name="text"> + <string>Bytes</string> + </property> + </item> + <item> + <property name="text"> + <string>16-bit Words</string> + </property> + </item> + <item> + <property name="text"> + <string>32-bit Words</string> + </property> + </item> + <property name="name"> + <cstring>m_comboSize</cstring> + </property> + <property name="enabled"> + <bool>false</bool> + </property> + </widget> + </grid> + </widget> + </hbox> + </widget> + <spacer> + <property name="name"> + <cstring>spacer1</cstring> + </property> + <property name="orientation"> + <enum>Vertical</enum> + </property> + <property name="sizeType"> + <enum>Expanding</enum> + </property> + <property name="sizeHint"> + <size> + <width>250</width> + <height>16</height> + </size> + </property> + </spacer> + </vbox> +</widget> +<connections> + <connection> + <sender>m_checkManual</sender> + <signal>toggled(bool)</signal> + <receiver>m_comboChannels</receiver> + <slot>setEnabled(bool)</slot> + </connection> + <connection> + <sender>m_checkManual</sender> + <signal>toggled(bool)</signal> + <receiver>m_editSamplerate</receiver> + <slot>setEnabled(bool)</slot> + </connection> + <connection> + <sender>m_checkManual</sender> + <signal>toggled(bool)</signal> + <receiver>m_comboEncoding</receiver> + <slot>setEnabled(bool)</slot> + </connection> + <connection> + <sender>m_checkManual</sender> + <signal>toggled(bool)</signal> + <receiver>m_comboSize</receiver> + <slot>setEnabled(bool)</slot> + </connection> +</connections> +<layoutdefaults spacing="6" margin="11"/> +</UI> diff --git a/plugins/encoder/sox/k3bsoxencoder.cpp b/plugins/encoder/sox/k3bsoxencoder.cpp new file mode 100644 index 0000000..ecae2e4 --- /dev/null +++ b/plugins/encoder/sox/k3bsoxencoder.cpp @@ -0,0 +1,482 @@ +/* + * + * $Id: k3bsoxencoder.cpp 731310 2007-10-31 10:30:05Z trueg $ + * Copyright (C) 2003 Sebastian Trueg <[email protected]> + * + * This file is part of the K3b project. + * Copyright (C) 1998-2007 Sebastian Trueg <[email protected]> + * + * This program is free software;
