Wrapper for buzzmachine sound generators and effects.

Details

gstbml_calculate_buffer_frames ()

void                gstbml_calculate_buffer_frames      (GstBML *bml);

update the buffersize for calculation (in samples) buffer_frames = samples_per_minute/ticks_per_minute

bml :

gstbml_convert_names ()

void                gstbml_convert_names                (GObjectClass *klass,

Convert charset encoding and make property-names unique.

klass :

 the instance class

tmp_name :

 name to build name and nick from

tmp_desc :

 desc to build desc from

name :

 target for name

nick :

 target for nick

desc :

 target for description

gstbml_dispose ()

void                gstbml_dispose                      (GstBML *bml);

Dispose common buzzmachine data.

bml :

 bml instance

gstbml_fix_data ()

void                gstbml_fix_data                     (GstElement *elem,

Fixes elements that output denormalized values (sets them to 0.0). Also adjust gap-flags. unfortunately this is quite expensive, although extra gap flags help.

elem :

 the element instance

buf :

 the data buffer

has_data :

 indication wheter the buffer has values != 0.0

gstbml_get_param ()

Read a parameter according to type from addr into the value.

type :

 parameter type

addr :

 the address pointing to the value

value :

 the target

gstbml_set_param ()
