Hi everybody, I have been using speex-1.2beta1 and my input data is 8-bit unsigned so I know that I should convert from 8 to 16 bits. I've done the convertion as following. for(int i=0; i<160; ++i) { input_frame[i] = (short)( (data[2*i] << 8) | data[2*i+1]); } When my codec application didn't work right, I think that the reason is an error at this

Hi everybody, I have been examining on how I can use speex completely so I have one more question. I looked at examples and source code and it goes on. speex_bits_insert_terminator is called in speex_bits_write function. Shall I call this method one more time anywhere? Because in speexenc project, firstly speex_bits_insert_terminator is called then speex_bits_write is called when we assume that

Hi everybody, I need clarification about speex_bits_write function usage. There is an example usage of it. nbBytes = speex_bits_write(&bits, cbits, MAX_FRAME_BYTES); I examine the content of this function and which value should I set to MAX_FRAME_BYTE. In speexenc project, it is 2000 and in manual it is 200. For example, I set it to 200 but the length of bits->chars is 250

...ere to make sure there's no buffer overflow and that's it. If you know that at the bit rate you're using the output is 20 bytes, then you can choose to allocate a 20-byte buffer and let speex_bits_write() know that. Same idea as e.g. strncpy(), which is safer than strcpy(). Jean-Marc yaseminyilmaz wrote: > Hi everybody, > > I need clarification about speex_bits_write function usage.

Hi all and Jean-Marc, Firstly thanks a lot to you for helps, at last I accomplished to use speex-1.2beta1 in my speech application. I try to understand speex source code and improve speech quality. The problem in my application (like many people in the list says) is noise. So I've added VAD in preprocessor as following: int param_enabled = 1; int param_disabled = 0; int sampling_rate

Hi SAITAMA Taro, I have been using speex-1.2beta1 dll in our voice application written with C#. In order to use Speex correctly firstly I advice to you examination speexenc and speexdec projects. I have used unsafe code and fixed statements in C#. I have added following method to library and I used that instead of speex_encoder_init simply. void *speex_encoder_init_new(int modeID) { const
