ArcSoft Delivers AMR And Midi/SP-Midi Codecs Solutions For Mobile Device Applications Enabling sound technologies for Mobile Devices FREMONT, Calif.--June 25, 2003--ArcSoft, Inc. the leading provider of digital multimedia software, today announced the availability of an Adaptive Multi-Rate (AMR) and Musical Instrument Digital Interface/Scalable Polyphony- Musical Instrument Digital Interface (Midi/SP-Midi) Codecs. The AMR and Midi/SP-Midi Codecs are multimedia sound solutions optimized for the following operating systems: -- Symbian 6.x and Symbian 7.0 for the Nokia S60 camera phone -- UIQ -- Palm OS 5.x -- MicroSoft Pocket PC -- Smartphone Based on ArcSoft's award winning multimedia and mobile technologies, AMR and Midi/SP-Midi Codecs allows device manufactures and software developers to better streamline their development process by integrating our audio engines seamlessly for their mobile solutions. It offers the standard compliant implementation of key components to allow flexibility for complex mobile solutions. ARM Codec is a speech coder for compression/decompression, is a piece of software that compresses digitized speech to reduce transmission channel or storage capacity requirements, and then decompresses received samples to reconstruct the original speech signal with minor loss in signal quality. Each speech coder is assigned a subjective measure that defines its closeness to "toll quality", a measure of acceptance for telephony applications. In order to interwork across different communicating equipment, a speech coder must conform to specified standards. ArcSoft has developed speech coders in conformance with several such standards. Midi is a protocol that supports musical instruments maker by enabling music recording or playback over a digital synthesizer. Midi does not present musical sounds directly; rather, it transmits data related to musical files. "Mobile devices such as cellular phones and PDAs are now appearing on the market with audio, video, and other compression/decompression functions integrated into their functional lineup," said Todd Rumaner, vice president of sales and marketing for ArcSoft. "In support of these functions, ArcSoft is offering advanced technology capabilities to developers, helping them to minimize their development resources and increase their time-to-market." AMR and Midi/SP-Midi Features: AMR -- Compliant with 3GPP AMR Speech codec standard -- Support CELP, frame muting, and VAD etc. -- Support read and write AMR file format (RFC 3267) -- Provide real-time encoding and decoding framework Midi/SP-Midi -- Compliant with MIDI and SP-MIDI standards provided by MMA and 3GPP -- Provide wavetable-based sound synthesis technology -- Support 4 - 64 polyphony midi content -- Support SP-Midi (3GPP + MMA) and GM1 content (MMA) in the standard MIDI file format. -- Provide configurable instrument bank including standard GM1 sound set with 128 melodic timbres and 47 percussive timbres.
