Convert XVID to AMR
|
Total Audio MP3 Converter converts XVID files to AMR format.
The software is an all in one audio converter that supports more than 90 audio
and video files as input, and converts to popular formats such as MP3, WAV, AAC,
M4A, OGG, WMA, and AMR.
Total Audio MP3 Converter also supports batch conversion, and is full compatible
with Vista and Windows
7.

What is XVID?
Xvid (formerly "XviD") is a video codec library following the MPEG-4
standard, specifically MPEG-4 Part 2 Advanced Simple Profile (ASP). It uses ASP
features such as b-frames, global and quarter pixel motion compensation, lumi
masking, trellis quantization, and H.263, MPEG and custom quantization matrices.
Xvid is a primary competitor of the DivX Pro Codec (Xvid being DivX spelled
backwards). In contrast with the DivX codec, which is proprietary software developed
by DivX, Inc., Xvid is free software distributed under the terms of the GNU General
Public License. This also means that unlike the DivX codec, which is only available
for a limited number of platforms, Xvid can be used on all platforms and operating
systems for which the source code can be compiled.
What is AMR?
Adaptive Multi-Rate (AMR) is an audio data compression scheme optimized for speech
coding. AMR was adopted as the standard speech codec by 3GPP in October 1998 and
is now widely used in GSM and UMTS. It uses link adaptation to select from one
of eight different bit rates based on link conditions. AMR is also a file format
for storing spoken audio using the AMR codec. Many modern mobile telephone handsets
will allow you to store short recordings in the AMR format. There also exists
another storage format for AMR that is suitable for applications with more advanced
demands on the storage format, like random access or synchronization with video.
This format is the 3GPP-specified 3GP container format based on ISO base media
file format.
Key Features:
- Sampling frequency 8 kHz/13-bit (160 samples for 20 ms frames), filtered to
200-3400 Hz.
- The AMR codec uses eight source codecs with bit-rates of 12.2, 10.2, 7.95,
7.40, 6.70, 5.90, 5.15 and 4.75 kbit/s.
- Generates frame length of 95, 103, 118, 134, 148, 159, 204, or 244 bits for
bit rates 4.75, 5.15, 5.90, 6.70, 7.40, 7.95, 10.2, or 12.2 kbit/s, respectively
- AMR utilizes Discontinuous Transmission (DTX), with Voice Activity Detection
(VAD) and Comfort Noise Generation (CNG) to reduce bandwidth usage during silence
periods
- Algorithmic delay is 20 ms per frame. For bit-rates of 12.2, there is no 'algorithm'
look-ahead delay. For other rates, look-ahead delay is 5 ms. Note that there is
5 ms 'dummy' look-ahead delay, to allow seamless frame-wise mode switching with
the rest of rates.
- AMR is a hybrid speech coder which uses Algebraic Code Excited Linear Prediction
(ACELP)
- The complexity of the algorithm is rated at 5, using a relative scale where
G.711 is 1 and G.729a is 15.
- PSQM testing under ideal conditions yields Mean Opinion Scores of 4.14 for
AMR (12.2 kbit/s), compared to 4.45 for G.711 (u-law)
- PSQM testing under network stress yields Mean Opinion Scores of 3.79 for AMR
(12.2 kbit/s), compared to 4.13 for G.711 (u-law)
