Asterisk wav codec

Frequently at work and at home I need to convert audio files into a compatible format to use with either Cisco Call Manager, Contact Center, or Asterisk for your MOH message on holdIVR interactive voice responseand other types of pre-recorded messages.

In the form below, you can upload an audio file and download a converted copy in a format compatible with your phone system. The WAV is actually a ulaw encoding with a wav extension, but everything seems to like it. The FFmpeg command used to perform the conversion on another system will be displayed should you choose to do so. Please leave a comment if you found this tool useful. Happy encoding! Great tool, thank you! Thank you for offering this free service… I converted a wav file to a Talkswitch on hold music file in no time.

Thank you! I will be back! Big thanks for the tool! Thanks again!

What am I doing wrong? How do I get an option to download the converted file? You do not need to register. I was trying to use your online audio conversion tool to convert an MP3 file.

Entered information for all the correct fields entered the security challenge and submitted my request. After you click Submit, a download link for your audio file should appear just below the form.

You can also use the ffmpeg command displayed beneath that to do the conversion offline with you own local copy of ffmpeg. Thank you for taking the time to report a potential problem with the site.

Moderators: muppetmaster, ModeratorSupport. I have tried to record a number of test audio files in wav formats to be played as MusicOnHold and it looks like a number of wav formats, bitrate, frequency is limited. I am looking for audio recorder supporting Asterisk audio codecs. I have listed Asterisk installed audio codecs with show audio codes command as g, gsm, ulaw, alaw, g, adpcm, slin, lpc10 g, speex, ilbc but need more detailed specification on wav file format to be played by Asterisk.

For GSM, I believe you have to capitalise the. WAV and not for signed linear. Ideally you should create MOH variants for all the codecs that your callers might use.

In some cases, it is useful to use G. If so, what option should be selected. Another my question is how to use Audacity audio filters to discover what distortion come with sound from Asterisk, playing audio files to a sound card via Celliax audio channel. I would imagine that rather a large amount of work has been done on those areas already, although most of it will be in academic journals for which you will have to pay. I repeat that the sorts of distortion you get will not be simple. Simply substracting the time domain input from the time domain output may indicate a much greater degree of corruption than really exists, because the codecs will be deliberately discarding information that is not relevant for speech, which may result in phase shifts and whole missing frequency bands.

In common VoIP scenarios, codec issues will be solely the responsibility of the phones. Asterisk and the network will only contribute to packet loss. If you want the best quality from MOH, you will convert it to the codec used by the phone, offline, so that the runtime CPU load is minimised.

I experimented with Audacity to export MOH playable audio file and failed. Are you aware of audio samples library MOH playable files mono, 8 bit, Hz, 64 kbps to let me download and play Atserisk audio quality test MOH samples?

Windows Sound Recorder. I imagine Audacity will. Actually, I made a mistake in that Asterisk. I suspect Audacity can. They are due to gaps in the data stream. Also, the PSTN audio quality is quite low and mobile phone audio quality is a lot lower, especially for music.If the local host address of your system is See below for an example config. The sangoma translator module is designed to prevent such an issue, only if it loads AFTER asterisk codec translators.

If Asterisk stops responding shortly after loading, it could be an issue with the firewall settings on your system. If the sngtc server is listening on another port, then make sure that port is allowed through the firewall.

If the issue persists after checking the above, the firewall might still be causing the issue, at which point, all firewall entries should be cleared. To check all firewall entries run:. NMI received. After installing the transcoder, asterisk may fail to load. Then asterisk should load properly and all the codecs registered by the transcoder will begin to load.

If the network driver is not present, please follow the network driver installation procedure. The Ethernet interface for the Sangoma transcoder is not up. This can easily be verified by running the command:. This can be easily verified by running the command:.

The cost values for the sangoma codecs in 'core show translations' will be very high compared to the asterisk codecs by design. When a Sangoma codec is registered, asterisk will be forced to use the Sangoma codec if a translation is required by that path, since only unique codec paths can be registered in asterisk. However, it is important that the Sangoma codecs are only used when a translation is required by that codec, and not used as an intermediate step for a translation for a separate codec.

Testing the transcoder is easy. Ensure it is configured first as shown in the installation steps.

Additionally file format modules are provided to handle writing to and reading from the file-system. The tables on this page describe what capabilities Asterisk supports and specific details for each format. There are three basic requirements for making use of specific audio or video media with Asterisk. For audio or video capabilities that require a module - you should make sure that the module is built and installed on the system.

Audio or video capabilities for Asterisk are used on a per channel or per feature basis. To tell Asterisk what CODECs or formats to use in a particular scenario you may need to configure your channel driver, or modify configuration for the feature itself. We'll provide two examples, but you should look at the documentation for the channel driver or feature to better understand how to configure media in that context.

We set the option "format" to a string of file format names. Asterisk supports 8, 16, and 32kHz Speex. Use of the 32kHz Speex mode is, like the other modes, controlled in the respective channel driver's configuration file, e. The complete list of supported sampling rates and file format is found in the expansion link below:. Users can create bit Signed Linear files of varying sampling rates from WAV files using the sox command-line audio utility.

This has resulted in several practical changes to Asterisk that will benefit its users. Note that the additional codecs discussed here are available for use in Asterisk's SIP channel driver, only.

Versions of Asterisk prior to 10 supported bit Signed Linear sampled at 8kHz and at 16kHz versions 1. New to Asterisk 10 is support for a much wider range of sampling rates. The complete list of supported sampling rates and file format extensions is:. Users can create bit Signed Linear files of varying sampling rates from WAV files using the sox command-line audio utility. The resulting output.

Asterisk 1. Asterisk 10 now supports 8, 16, and 32kHz Speex. Use of the 32kHz Speex mode is, like the other modes, controlled in the respective channel driver's configuration file, e. In this example, we have created three SIP peers for 3 different devices.

The first, mypeer, supports only the 8kHz sampling of Speex; the second, mypeer2, supports only the 16kHz sampling of Speex; and the third, mypeer3, supports the new 32kHz sampling of Speex. For comparison, here are some Speex samples, saved as WAV files in. Asterisk 10 adds pass-through support for the CELT codec. CELT provides low-delay transmission of high-quality audio. Unlike many other codecs that are focused on the transmission of human speech only, CELT is suitable for the transmission of both speech and audio, e.

CELT is configured in codecs. Represents the duration of each frame in samples. Defaults to and should only be defined if a client does not use the default size. This option allows the codec to split 20ms frames into multiple frames in an anticipatory way.

Thus, with 20ms frames at 48kHz are samples, the packet is large. So setting framesize to20ms frames are transmitted in two sample packets. These codecs cannot be dynamically changed while Asterisk is running. In order to make changes, an Asterisk restart is required. In this case, we have defined 3 peers, each with a different CELT sampling rate.

Thus, you'd probably want to set at least two of them to the same CELT rate, so they could call each other. For CELT-calling, there are not a host of options on the client side.GitHub is home to over 40 million developers working together to host and review code, manage projects, and build software together.

Asterisk 1. To compile the codecs it is recommended to install Intel IPP libraries for better performance. Alternatively, download and install Bcg - a slightly slower implementation written in portable C Only G.

The codecs are tested against Bcg 1. Users of IPP 9. Check available options with. Specify --prefix in case Asterisk is installed in non-standard location.

This option is for outgoing voice stream only. It does not affect incoming stream that should be decoded automatically whatever the bit-rate is.

There are also two Asterisk CLI commands g debug and g debug to print statistics about received frames sizes. This can aid in debugging audio problems. Bump Asterisk verbosity level to 3 to see the numbers. Build it with supplied build-astconv. Use codec module that was compiled against same Asterisk version the astconv was built against.
