AstroStack is an easy-to-use astronomical imaging and processing tool geared towards the use of inexpensive webcam CCDs. It provides a very tunable environment to produce the best quality images. It supports the following features: tunable webcam sampling; image stacking (averaging, additive etc.); pre and post-capture gamma (brightness) and contrast correction; dark-shot CCD calibration (subtractive); and an internal 16-bit grey-scale format for optimal resolution.
Audible TTS reads text aloud from other apps, the clipboard, or from text files. It can get text from applications such as Feedme or K9-Mail, the clipboard (using Copy and Paste), or from files on the MicroSD card. It also reads each sentence using the proper language and voice in mixed texts, without having to select it manually. You must have installed a voice synthesizer (such as PICO or SVOX) and voices for the languages to be used. It currently supports German, English, Spanish, French, Italian, Dutch, Polish, Portuguese, Turkish, Russian, Arabic, Korean, Chinese, and Japanese.
AudioScout is a distributed audio content indexing system. It can index a large collection of audio content for the purpose of later recognition of unknown signals. Robust to noise, different encodings, and other types of distortion, it can be used for a variety of applications including duplicate detection of files, identifying music, as well as more sophisticated uses involving the enforcement of copyrights and ensuring lawful use of content.
AudioSpace calculates the amount of storage required by an audio recording of a given duration, for different sampling rates, resolutions, and numbers of channels. The calculation may be made for uncompressed audio data or for several types of compression. A variety of units may be selected for reporting the result. The calculation may also be inverted to determine the maximum duration of audio that will fit into the available storage.
audiopreview is a command-line tool that plays previews of many audio file types (Ogg, MP3, etc.), video file types (AVI, MPEG, Real, etc.), and Internet streams. It can also be used as a regular command-line media file player (i.e. play the files entirely like yauap or mpc123 would).
AutOrg aims to be a text editor, personal organizer, local wiki, secure agenda, and everything in between. For the user interface, it gets its inspiration from text-based minimalism, still providing advanced features for publishing, encrypting, and sharing information. It uses Emacs Org-mode and other extensions, and its main binary distribution runs on a Mac OS X desktop.
