Evgueni, Don't listen to this guy. The last thing someone confused about types should use is a union. Listen, whatever types you're using, you're just dealing with data in memory. For an array, it's just a big block of data in memory. You need to know how that data is stored in memory. For audio data, WAVEFORMATEX tells you that with its contents. Don't let types

Hello, I know my question has been asked before because I spent the last week searching the web for how to use Speex in combination with WaveIn/WaveOut and I ran into a few posts, but none of them answer the question. There is still a lot of confusion how to use WaveIn/WaveOut and Speex by junior developers such as myself. Even after examining code for SpeexDec and SpeexEnc, I cannot get clear

Thank you for such a quick response. The only reason I started with Char buffers is because WaveIn and WaveOut on Windows XP accept/emit WAVEHDR structures, which store audio data in LPSTR, which is Char*. typedef struct { LPSTR lpData; DWORD dwBufferLength; ... } WAVEHDR; When I was going from Char to float and back looked very wrong to me as well, but I was just not

Again, thank you for helping me. I know this might seem like a trivial matter to you and other experts in the field, but believe me, there are a lot of programmers, whose posts I saw on the web, who tried to use WaveIn/WaveOut and Speex and failed. As I understand it, WaveIn just buffers audio data according to the bit rate specified. So, if we use waveFormat.wBitsPerSample = 8, then each Char of

Hi, My results are getting out of order after I do the following command: count = result.inject({}) { |hsh, row| hsh[row[''name'']] = row[''count''].to_i; hsh } Why? Here are more specifics: My complete method is this (based off of acts_as_taggable code - not'' DHHs, but the original one): def self.sql_to_count_plays(lookback) sql =

Does anyone know how to get this MIDI program working under Wine? In fact, I have it running, but as it starts I get a message saying: "There are no MIDI output drivers installed" and there is no sound from the program. Otherwise it seems to run correctly. I'm using the most recent version of CodeWeavers Wine under Mandrake 8.0 - do not have Windows proper installed on this

The code on http://blog.craz8.com/articles/2005/10/28/acts_as_taggable-is-a-cool-piece-of-code is based on the acts_as_taggable gem,anybody has done that using the acts_as_taggable plugin?thanks! btw:the code above uses the tag_count method,which is defined in the gem: def tags_count(options = {}) options = {:order => ''count DESC''}.merge(options)

I'm not sure what input/output format you're trying to use, but it looks wrong. You're using the float functions that take +-32767 values and you're feeding (or converting) chars. Unless your machine has very special chars (which I doubt), a +-32767 value just isn't going to fit in. This has nothing to do with Speex BTW, it's just handling the audio data properly.

hi, Is it true the flac encoder can compress music better when the complexity of the music is low? I'm compressing some tunes of old MS DOS games (pc speaker, sound blaster 16 OPL3 chip music) and I saw a *huge* compression ratio (some files where only 1/3th of the original file in filesize after compressing to flac), so I was wondering if less complex music always means better compression.

Hello Friends, I am trying to use speex-1.2beta3 version for echo cancelling. On my WinCE board I am using WaveIn/WaveOut functions to record and playback audio. I am receiving audio data on udp socket, then playing it on speaker using WaveOutWrite function. I registered callback to capture microphone data, then data chunk came from socket ( which I played on speaker) and data captured from

Dear Rails groups, thank you for all the previous helps in this group, and me being a newbie is getting more comfortable with rails and now I finish most of the scaffold modification without much problem. My question is(I know it''s absolutely basic questions but I''m a real outsider :~( ) I have been developing in my own pc, now my office ''s other people will test on it,

Hi, I recently changed my motherboard to Gigabyte GA-7DPXDW+ and I can't get onboard AC97 sound to work. I added 'device pcm' to my kernel config file and sndstat returns FreeBSD Audio Driver (newpcm) Installed devices:", nothing ;( Any hints ? I'm running FreeBSD 4.8-STABLE

Hi, My name is Patrick, i am french, and i am developping a softphone for pocket PC using speex. Sorry in advance for my bad english. So i have make an GUI in C# that use the speex functions through dll write in C++. And the encoding and the decoding using speex seems to work not too badly.(i test with a wave file) My problem is that i need to get audio data from the microphone. In order to do

Hi, I am trying to encode raw wave data stored in a buffer using the Speex API (The raw wave data is created using the waveIn* functions - probably irrelevant information here). It is a 5 second clip, 16bits/sample, 8000Hz mono (which gives a buffer size of 80kb for the wave data). I have followed the exact procedure found in the manual available from the web site, except that

Hi Guys, I am trying to incorporate the speex AEC into my RTP stack. Trying to diagnose why the echo is not being cancelled I enabled DUMP_ECHO_CANCEL_DATA as per the docs. The problem is that the dump files the AEC generates are of different size. As I understand this and looking at echo_diagnostic.m, the files are supposed to be of same size. Can someone give me a hint as to why this could
