The three Digigram PCXpocket cards are designed primarily for specialized Digigram Powered applications that are written by our development partners to run on the cards' on-board digital signal processors. For standard third-party audio and music production software on Windows or Mac OS platforms, the Digigram VXpocket should be considered.

Significant on-board DSP enables the PCXpocket 440 to manage a variety of Digigram Powered (np SDK) applications, including those that can take advantage of its LTC (SMPTE) time-code input for synchronization. Additional DSP functions enabled by the np SDK include MPEG (Layer I and II) and GSM encoding and decoding, variable sampling frequency, and sophisticated audio processing. The PCXpocket 440 may also be used with applications using Microsoft's WAVE protocol.

A unique "Cable Cosse" provides positive connection to the PC Card on one side and to a fan-out of audio cables on the other. Analog connectors are XLR and the SPDIF and LTC connectors are phono (CINCH).

A portable and powerful digital audio workstation is created when the PCXpocket 440 is coupled with Digigram's Xtrack suite of digital audio production tools.

• The PCXpocket 440 is full duplex, offering simultaneous and independent record and playback capabilities.
• PCM encoding/decoding resolutions are 8, 16, or 24 bits.

When using applications based on the Digigram np SDK with the PCXpocket cards:

• Real-time mixing of multiple sound files, level adjustment, panning, cross fade, punch-in/punch-out, scrubbing, time-stretching, pitch-shifting, and format and frequency conversions are performed on the DSP of the cards.
• Cards perform real-time, simultaneous MPEG Layer I and Layer II compression and decompression during record and playback. Support provided for Layers I and II of the MPEG Audio standard (ISO 11172-3) and the low sampling frequencies of the MPEG-2 Audio standard (ISO 13818-3).
• Cards perform GSM encoding and decoding.
• Multiple applications may share the resources of a single card.
• Analog inputs and outputs may be configured as one stereo or two mono channels.
• Interboard synchronization is possible for operation of two PCXpocket 440s in one laptop.
