VXpocket 440
The PCXpocket 440 has four mono (or two stereo) analog inputs and four mono (or two stereo) analog outputs. In addition, an SPDIF input can be used in place of the first stereo input pair and an SPDIF output operates in parallel with the first stereo output pair. If more inputs and outputs are needed, two PCXpocket 440s can be synchronized in the same laptop.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.
Features
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.
