Precorder - Version: Alpha 0.5.3
(22 Apr 2010)
Summary
Precorder is the next generation audio recording app that has been developed by WebOS Internals. Currently, it allows for audio capture from the built in microphone as well as through the headset. It also features a "media capture" mode, which can record virtually any audio stream that is currently playing. Future plans include bluetooth support, timer, ability to record calls, visualizations, and possibly a voice activation mode.
Precorder uses the pulsesrc plugin directly through a gstreamer pipeline, so in theory it allows for more flexability in the future such as variable controls for stream and bitrate, various plugins for mp3. And because it uses a C based service, it can be removed with the Orange+Tap method.
Status
Precorder is ALPHA SOFTWARE developed primarily by ZSoc & PuffTheMagic of WebOS Internals with assistance from a number of other developers (as listed in the Maintainers field in the package metadata). Thus, it is only available through the WebOS Internals testing feed.
Recent Changes
Even though Precorder in alpha state is not available for download in Preware (it will be when it goes into beta), once you install Precorder it appears in the Installed Packages section and you can see the package changelogs there.
Donations
Please see the official PreCentral thread first post at http://forums.precentral.net/2059462-post1.html for the donation link. Since this is a wiki that anyone can edit, we do not put the donation link here.
Installation
Note that you cannot install the packages using any other method than the methods below. Specifically, fileCoaster is not able to install these packages.
Installation
Precorder will be added to main Preware once it reaches beta status. Until then, please install Precorder from Preware/WOSQI using the testing feed. See http://www.webos-internals.org/wiki/Application:Preware#Adding_Custom_Feeds for more information on how to do add the testing feed to Preware.
License
The GStreamer Service package is MIT Open Source licensed. The Precorder application is GPLv2 Open Source licensed.
Operating notes
When precorder is first launched you will see the main screen. Precorder will default to the Microphone mode. Tap the Record button to start recording audio. Once you have finished capturing, hit the Stop button. There might be a slight wait before you can hit Record again.
Tap the Media Capture button to record currently playing audio. Note that some apps (Video, Youtube, etc) will stop playing if the card is minimized. To capture audio from these sources, you must start the recording in Precorder then switch to the other app and start playback.
Customization
There are several features of Precorder that can be customized. All of these settings are available via the preferences option within the Precorder menu. The table below lists all possible preferences. Options in bold represent defaults.
