Which CODECs are supported for file recording/playback?

Play/record function supports the following CODECs at a sampling rate of 8000 times per second:

1) For standard wav files: Single-channel A-Law, μ-Law and 8-/16-bit linear PCM, IMA-ADPCM, Dialogic-ADPCM (VOX), MP3, GSM and G.729A are supported. For stereophonic recording which is invoked by SsmRecStereoToFile, A-Law and μ-Law are supported.

2) For plain files (i.e. files without header information): Single-channel A-law, μ-law, 8-/16-bit linear PCM, IMA-ADPCM, Dialogic-ADPCM(VOX), MP3, GSM and G.729A are supported.

3) For standard MP3 files: Single-channel MP3 is supported.

Which compression format does recording use, and at what rate?

The following recording compression formats are supported:

1) IMA-ADPCM or Dialogic-ADPCM (VOX): Compression rate of 2:1, i.e. voice data are generated at 4kbps.

2) GSM: Compression rate of 5:1, i.e. voice data are generated at 1.6kbps.

3) MP3: Compression rate of 8:1, i.e. voice data are generated at 1kbps.

4) G.729A: Compression rate of 8:1, i.e. voice data are generated at 1kbps. Tivo usb devices driver download for windows 10 32.

How to play WAV files recorded by a sound card with a Synway voice board?

The files can be directly played by Synway voice boards if the file format is supported by our product. Otherwise, they have to be converted into a supported wav format with third-party software tools such as Cooledit.

Why are noises sometimes heard in the process of file playback?

This generally happens when voice data are corrupted or when incorrect play-format is used to decode an unformatted voice file. Another reason is the voice codec being used to play files is unsupported by Synway boards.

How to play or record GSM, MP3 voice files?

To play or record GSM, MP3 voice files, you should first modify the configuration item under Section [SystemConfig] in the file ShConfig.ini to GsmCodecEnable=1, and be sure to install necessary codec engines (The engine for GSM is usually carried by Windows operating system while that for MP3 could be acquired from the DEMO package released at our website).

Key Values

Synway offers a wide range of product portfolios for use in all kinds of recording applications including call recording and call logging in legislature, call centers, financial dealing, and control/command operations.

Passive E1/T1/J1 Recording

1/2/4 trunks (T1/E1/J1) per card

Advanced data processing DMA technology

Compatible with PCI(X) or PCI-express interface

The DTP is widely used as a reliable tool for call logging applications developers to passively tap E1/T1/J1 trunks in high-density telephony environments.

Synway Sound Cards App

With multiple signaling capabilities and high compatibility with international standards, the DTP series has been widely used as a reliable and cost effective tool by call recording application developers to passively tap E1/T1/J1 networks in a variety of complex telephony environments. Used by the leading call recording solution providers since the 1990s, the DTP series has been optimized to fit the toughest demands and most competitive environments because of its unrivalled cost advantages and world-class robustness.

As a proud milestone in call recording hardware design, the DTP series is E1/T1/J1 interface software configurable, supports 4, 2 or 1 dual span taps per slot, and can flexibly fulfill various requirements. Specifically, by providing on-board advanced DSP algorithm and DMA processing capability, the DTP series helps minimize host CPU resources and outperforms all competitor products in the toughest application scenarios. This includes better performance and higher scalability up to 1200(40E1)-channels simultaneous call logging. For these reasons many leading developers worldwide depend on the DTP series to create robust high capacity systems in complex central office as well as high-demand Telco environments.

The DTP series also leverages dedicated DSP chipsets to process a range of high-ratio compressions, such as license-free G.729 and GSM. This robust architecture further releases host processor resource from overloading and assures efficient data storage and high robustness for data transmission in the most difficult situations. The DTP series provides call logging application developers with a complete range of options, portfolios containing half/full length, E1/T1/J1 configurable, CAS/ISDN/SS7 protocols and more versatility. Conveniently DTP series can be installed into most server categories and computer types. All of its new-generation portfolios are PCI-express or PCI(X) form factor, half-length card.
