Qualcomm Incorporated (NASDAQ: QCOM), a leader in wireless communications and advanced electronic messaging solutions for the Internet, today introduced PureVoice™—a revolutionary voice coding technology for a wide range of voice-enabled software applications. The first implementation for PureVoice is a freeware player-recorder, which incorporates a plug-in for Eudora® client software and can be downloaded from Qualcomm's Eudora website.

The PureVoice plug-in for Eudora allows users to record, send, receive and play back voice messages directly from within the Eudora software interface with exceptional voice quality and very swift transmission times. The PureVoice player-recorder also works with virtually any MAPI-compliant email software that supports attachments.

"PureVoice's superior technology means that users can send and receive voice messages with outstanding clarity and unprecedented speed, which truly enriches the user's experience and enhances communication," said Jeff Jacobs, vice president and general manager of Qualcomm's Eudora division. "As the leader in Internet messaging we intend to take a dominant role in extending the functionality of email and making email enabled voice messaging pervasive."

Based on Qualcomm's superior voice compression technology, originally developed for voice transmission over IS-95 CDMA wireless networks, PureVoice provides landline quality voice transmission in Qualcomm's Personal Communication System (PCS) and cellular phones.

PureVoice technology offers smaller file sizes and better sound quality and can reduce file size and transmission time by over a factor of 10, compared to other common formats such as .wav. For example, a typical one minute voice mail message in a .wav file would take up about one Mbyte and take over seven minutes to transmit using a 28.8kbps modem. The same voice mail coded using the PureVoice technology would be less than 90 kbytes in size and take less than 45 seconds to transmit.

The PureVoice plug-in takes advantage of Eudora software's Extended Messaging Services Application Programming Interface (EMSAPI), a Qualcomm-developed API that makes it easy for third party developers to add additional functionality to Eudora client software.

Qualcomm intends to license PureVoice technology to OEM manufacturers and offer a Software Developer's Kit to third party developers in the near future.

The Qualcomm PureVoice player-recorder for Eudora Pro™ and Eudora Light™ software runs on Windows® 95, Windows NT® 3.51 or higher, and Apple® PowerPCs® running Macintosh® 7.x or higher platforms and is available free as a download at Qualcomm's Eudora division website at
