MiniBAE

From Legacy Portable Computing Wiki

miniBAE (mini Beatnik Audio Engine) is a mobile sample-based audio engine developed from 1999 to 2002. It is an optimized version of Beatnik Audio Engine for mobile usage, and was licensed to manufacturers such as Nokia, Danger, and Sony Ericsson. It was succeeded by mobileBAE in 2002, a rewritten version.

History

The technology was first developed by Steve Hales and Jim Nitchals in their video game company called Halestorm in 1991. At the time, it was called SoundMusicSys, appearing in many successful video games for Macintosh, and in Microsoft's WebTV devices. In 1994, Steve and Jim transferred the technology to Igor's Software Labs (aka IgorLabs), which Beatnik. (called Headspace, Inc. at the time) would eventually acquire.[1] Later, BAE appeared in 1997 as a browser plugin used to play "RMF" (Rich Media Format) files, a direct precursor to MXMF files that used proprietary bank formats instead of .dls. This format was a way of storing music in a small size, so people with a dial-up connection could download it relatively quickly.

BAE was also used in older Java versions (until JRE 7), and BeOS. Nokia started licensing miniBAE (a smaller version of BAE) in 1999,[2] but did not begin using it until the Nokia 3510 and Nokia 7650. It was used on many Nokia phones between 2002 and 2010, although after 2004 it had been deprecated in favor of MobileBAE and was only being used on low end S40 phones at this point. The last known phone to use it was the Nokia 2220 slide.

Danger's Hiptop/Sidekick devices also used miniBAE up until 2004-2005, when they switched to MobileBAE. A handful of Sony Ericsson phones running Symbian UIQ, such as the Sony Ericsson P800, also use the engine. Motorola are also alleged to have used it on some phones. MiniBAE was also ported to Linux, but not included in the source code release for an unknown reason.

Since the shutdown of Beatnik in 2011, the source code has been released under a BSD license.[3] An enthusiast who goes by the name zefie managed to get the code to work on Linux (ANSI, waveout only), and Windows.

MiniBAE sound banks

Sound bank name File size Creator Notes
HruskaNokia (Rev 5) 92.3 kB Jennifer Hruska Is an earlier version of SalterNokia. Despite what the name states, it was not used on any Nokia phones. It was designed by SONiVOX for Beatnik Inc.
SalterNokia (Rev 4) 92.3 kB Brian Salter This version introduced new ADSR/instrument management into the bank, though it still used HruskaNokia samples, unlike Rev8a which optimized the samples further.
SalterNokia (Rev 8a) 97.4 kB Brian Salter A small bank found in the miniBAE source code. It was not used on any Nokia phones. Used in early 'generic' Symbian releases, SDKs, and launch firmware of the Sony Ericsson P800.
UIQ bank 101 kB Brian Salter Used in early Sony Ericsson UIQ phones. Is a derivative of the 'SalterNokia' bank, but with more unique patches. The P900/P910 version has different equalization compared to the P800 (later firmware version)
Small bank 59.8 kB (70.7kB on phones with a camera) Brian Salter
Mikko Tillander
Used in mid/low-end S40 phones from 2002 to 2006. Informally known as the "Chippy" bank.
Large bank 306.7 kB (170.2kB on phones) Brian Salter Used in S60, S80, S90 and high-end S40 phones from 2002 to 2006.

Arne Schulze
Jussi Salonen
Used in the N-Gage phones as well as a few other phones such as the Nokia 7600. It sounds similar to large bank but it has extra instruments. It is named after Nokia 7600's codename.
Hiptop v1.0 ??? Peter Drescher Used on Danger's hiptopOS 1.0
Hiptop v1.1 224 kB Peter Drescher Used on Danger's hiptopOS 1.1, 2.0 and 2.3
