  • Forum Post: Re: Tone Generation (TDU) in VOLIB Release 1.0.0.1

    bogdank
    Hello Jonathan, The ti.mas.sdk component is used only by the unit test code within the VoLIB . As you could see it was not optimized at all (since we only used it for testing). Nevertheless, you are right, the tone generator there can be used for single and dual frequency tone generation. If you are...

  • Forum Post: VoLIB/Codec Server Integration

    Dennis E
    We have a need to integrate algorithms from the VoLIB into our existing codec server (for the OMAP3530/C64+). Our server currently contains a number of audio & video encoders and decoders, as well as a custom video processing algorithm we wrote in-house that uses DSPLIB 2.1, IMGLIB 2.01, and VLIB...

    Hi Dennis, First of all, I'd like to be sure that VoLIB is what you're looking for. VoLIB offers high-performance speech processing building blocks. All components in VoLIB support 8kHz sampling, though some offer configuration for 16kHz as well. If by "audio" processing you mean...

    Dennis E
    Thanks for the reply, Our purpose for looking at this library is to process the audio to detect the presence or absence of speech. 8kHz is probably fine. I know the VAU component supports XDAIS. Does it make more sense to try to export this component directly by our codec server or to write a "wrapper...

  • Forum Post: Re: VoLIB/Codec Server Integration

    CharlieF
    If the VAU is the only component you need, then I would just use the XDAIS API that it provides and not bother with any ECO API wrapper. Also, the VAU supports 16kHz if this would be preferable. If processing resources (MIPS) are tight, another option is the simple VAD (SVD) module of the voice processing...

    Hi Paul, Unfortunately, although the packages are visible under RTSC packages within the CCS environment, I don't believe they can be integrated in this manner (yet). What we have done in the past, to incorporate a VoLIB component into a Project, is to add the library and header file path...

    Hi Weichun, Just so I can understand the problem better, what is your end-goal? Are you looking to run the ECU within the simulator to better understand the operation, or are you integrating it into an existing codebase and trying to compile? Also, what VoLIB release are you using? If you are using...

    Hi Jonathan, Yes, voice discrimination is supported and should function properly. It has historically been used as a check to ensure voice-band data mode has been properly identified. If it reports "voice", the channel can save bandwidth and down-speed to voice mode. Where, specifically...

    Hi Weichun, Yes, the projects provided with VoLIB 1.0.1 are for CCS version 4 and above. Getting up and running with CCS version 4 can be a little vexing due to the new Eclipse environment, though I believe loading and building a project should be relatively easy. Try the following and let...

    Hi Weichun, Just curious -- do you have a config.bld file in your swtools directory? The installation should provide this. Regards, Charlie

  • Forum Post: Re: Help getting ECU in VoLIB to work.

    CharlieF
    Hi Paul, First off... no, unfortunately you can't disable delay line compression since the ECU is delivered as a compiled object. However, this should reduce your memory requirements -- even on C55x -- since we pack the PCM data in this case, two samples per word. Let me know what the call to...

    Hi Jonathan, You've identified a bug in the code. We're calling a NULL pointer from the TDU context for global memory pool buffer allocation without checking. We will enter a defect report that you can track here . Regards, Charlie

    Hi Kevin, This problem has been redirected to me -- I will be able to help provided this is a TDU issue. I've reviewed this thread and it sounds as though you had the TDU "working" for a while as long as you didn't change the detector context structure. Now though, with the original...

  • Forum Post: Re: volib c6p 1.0.1.2 tduOpen() exception

    CharlieF
    Hi Kevin, Good catch. The call to tduNew() checks the instance pointer (pointed to by **tduinst) and skips all buffer assignment if it is not NULL. This is done to ensure the TDU is using an "available" instance pointer (tduDelete() sets the instance pointer back to NULL). I would guess...

    Hi Benlu, I'm a little confused since VoLIB doesn't provide any voice codecs. Rather, it provides voice processing components and the codecs are available independently. Can you please provide more information? Best Regards, Charlie

    I see. The current VoLIB release does not support ELF, however release 2.0.0 will support ELF for both C64x+ (C674x) and C66x. This release is expected to be available before the end of the year. When VoLIB 2.0.0 is released we will announce it on this Forum. Best Regards, Charlie
