similar to: Speex newbie: win32 encoder and Java applet playback?

Hi! I?ve just discovered Speex, and sorry if this isn?t the right place to ask this, but I found no other mailing list (some projects have a "users" and a "developers" list separately, I guess this isn?t the case with Speex. If it is, please let me know). First, how I got here: 1. I?m looking for some low-bitrate codec to reduce the size of some very long (think 4-5+ hrs of

I'm new to Speex and I'm trying to compress audio using JSpeex in a servlet then play it back on the iPhone. I've managed to get Speex to compile on the iPhone by copying the speex and libspeex folders into XCode. I've read the sample code and the PDF documentation and I have a rough idea how to decode a raw stream. (I'm assuming the sampledec source works with raw speex audio

If I use Speex, JSpeex actually, to compress an otherwise valid wave file with zero lengths in the header would it impact the compression at all? Here's what I'm doing during compression in Java: AudioFormat wavFormat = ais.getFormat(); AudioFormat speexFormat = new AudioFormat(SpeexEncoding.SPEEX_Q5, wavFormat.getSampleRate(),

I have an audio file compressed by JSpeex that I'm trying to decompress on the iPhone. I've been trying to work from the speexdec example in an attempt to port the core logic to ObjC. I have a class that does the decode and passes the result back to another class. (currently the other class is a unit test.) My other class is writing the converted output to disk. I compare the results of my

Hi all, I'm having a playback issue I can't eliminate. I'm encoding 16khz mono WAV files (voiceover recordings) to speex using a quality setting of 4. In any standalone speex player e.g. winamp or using speex frontend etc. the files play fine, but in a jspeex environment there's a subtle high pitched beeping type distortion, mostly on the transients. The sound is similar to

I spent some more time with the Ogg and Speex format specs, and I realized that using the "application/ogg" MIME type is technically sound, since Speex is contained in an Ogg wrapper. To get full browser support, though, it is best to rename it so its file extension is "ogg". Some browsers do not support files where the MIME type and file extension are different, based on

Hi, AFE currently has a bug where it can't handle audio-only

Is Jspeex still being worked on? Is there somewhere I can send the code changes I've made to facilitate smooth streaming?

Hi, I am trying to implement a web application that allows the user to playback WAV files inside a web browser. __________ Background __________ - The file server stores audio files as GSM 6.10 or TrueSpeech encoded WAV files. - The web server (most probably ASP.NET on IIS) offers the client the ability to search audio files on the file server (a different machine). - The client will be

Essentially, the thing that's been holding up 1.2 was the AEC and preprocessor. The codec itself is pretty stable and I do not really see more work happening on it. As for the AEC and preprocessor, these are really open-ended project and I lack sufficient time to take care of them.

Thanks for the help folks, but I got this working a couple hours ago. =) I'm quite please after struggling with it for a few days. I just needed to take each audio tag from the FLV file and feed the contents of the tag (except for the first byte) to the jspeex decoder and write the results to a file. Jozsef - it is possible to specify 8KHz in the flash client and decode it as such. Speex

Thanks for your reply. I am using JSpeex so it is not possible to use the libs you mention. I looked a little at the source in http://jspeex.sourceforge.net but cant see where the length can be stored. Unfortunately, that project does not seem to be maintained - no replies to queries posted on the forums. Does anyone know how to store the length of a JSpeex clip in the header? thanks, Anil ---

This alias should be a great default addition to the bashrc... as it helps install packages to a CentOS system from the mounted install CD before you get networking up and running... alias localyum='yum --disablerepo=* localinstall' Does Red Hat care about Requests for Enhancement? or is filing a bug pointless?

The off dependencies are only for speexenc and speexdec, as far as I recall. If you omit those targets, you shouldn't have the ogg dependency issues.

Just an update, and a follow-up question: I'm making progress on this issue, and will likely have something working very soon, now that I understand how the jspeex transcoding classes work. Unfortunately, I will need to make a couple small changes to the jspeex source code. My question is - is anybody using jspeex for streaming speex-encoded audio? It works great for static audio, but seems

What is DRM? Why do we remove DRM from WMA WMV ? Have you download music and video from Windows Media Player, iTunes, Rhapsody, Napster, bearshare, Spiral Frog, BBC iPlayer downloads? These popular WMA music and WMV movie download programs among the music fans always come with a disgusting word - 'DRM'. DRM (Digital Rights Management) - The anti consumer copy protection that prevents

This is best answered by the jspeex folks, as it is the interfacing code that you are having problems with. That being said, it looks like, just as it says, you have asked for a conversion it cannot do -- you want it to convert PCM data to speex data at 44.1kHz sample rate -- speex only supports 8kHz in standard operation. It can also support 16kHz (wb) and 32kHz (uwb), but nothing outside of

Hello, I am completely new to Speex and make files but I'm looking to build/ run Speex on the iPhone for decoding and potentially encoding. I've read that you can just copy the source into an XCode project which I tried but I started getting all kinds of compile errors. (1000+) There were things like missing references to ogg header files and so forth. Could someone explain
