[Bluez-devel] SBC encoding Wav files

[Bluez-devel] SBC encoding Wav files

[Joe Samuel]

Hi,
Why is the sbc code accepting only au?
I tried a PCM wav file, changed the endianness here:
for (ch = 0; ch < sbc->channels; ch++) {
			int16_t s = *((short *)ptr);
			ptr += 2;
			priv->frame.pcm_sample[ch][i] = s;
		}

And of course, changed the header reading part; but it
looks like things are not as simple as that. The
encoded file sounds horrible (rather I would say, it
had nothing in it that sounds like the original).
Did I miss out something?

regards,
Joe

Joe,

If .pcm works and .wav doesn't, must be something with audio parameters 
extracted from wav header? I've never tried wav's and the earliest I can is 
the week after the next week... May be Brad has some ideas?

Regards,
    Victor.

[Brad Midgley]

hey

we just have a reference encoder. use another tool to convert to .au 
first. i'm not sure it's worth the effort to add more formats to the 
encoder when it's just for development.

to reiterate: we want the encoder to work transparently as a plugin 
inside alsa. maybe i'll be able to get back to that now.
