| As
well as delivering high performance speech/audio rendering
and streaming solutions, Brogent provides our customer
support for an increasing range of standard and new
speech/audio formats.
- G.723
G.723 is a standards-based voice codec designed for
video conferencing/telephony over standard phone lines.
It is optimized for real time encode/decode and provides
decent voice quality.
- MP3
MP3 is the optimal choice for low data rate applications
for making music available on network transmission.
MP3 decoder provides a set of options to facilitate
integration in larger project and provide quality/resources
trade-off.
- Adaptive
Multi- Rate
AMR enables better speech quality and increases the
capacity of the network, but does not require any
additional hardware investment.
AMR-NB is the default speech codec
for GSM 2+ and WCDMA 3G wireless system. It is developed
to preserve high speech quality under a wide range
of transmission conditions. AMR-NB operates at 8 bit
rates ranging from 4.75 kbps to 12.2 kbps.
AMR-WB(True Tone) is an adaptive
multi-rate wideband codec with bit rates ranging from
6.6 to 23.85 kbps. AMR-WB decoder is mainly used in
the 3GPP mobile phone standard. It enables the phone
to deliver enhanced multimedia messaging services
(MMS) – such as the recording and playing of
voice clips.
- MIDI
Musical Instrument Digital Interface (MIDI) is a technology
that represents music in the form of music notes.
As compared with other wave-formed digital music technologies
such as mp3 and CDs, MIDI contains individual instructions
for playing each individual note of each individual
instrument. This leads to the ultra-small file size
that is suitable for transferring files over limited
bandwidth networks (i.e. wireless). Polyphonic ring
tones, music players, and MMS messaging are the typical
applications of MIDI.
