Deprecated Opcodes

The following opcodes are deprecated. They are still distributed with Csound for backward compatibility. The new opcodes which are to be used in place of the deprecated ones are indicated within each of the following entries.

bformdec - Decodes an ambisonic B format signal into loudspeaker specific signals.
bformenc - Codes a signal into the ambisonic B format.
fin - Read signals from a file at a-rate.
hrtfer - Creates 3D audio for two speakers.
ktableseg - Deprecated.
pop - Pops values from the global stack.
pop_f - Pops an f-sig frame from the global stack.
ptable3 - Accesses table values by direct indexing with cubic interpolation.
ptable - Accesses table values by direct indexing.
ptablei - Accesses table values by direct indexing with linear interpolation.
ptablew - Change the contents of existing function tables of any length.
push - Pushes a value into the global stack.
push_f - Pushes an f-sig frame into the global stack.
sclag - Exponential lag with 60dB lag time.
sclagud - Exponential Lag (Deprecated).
scphasor - A resettable linear ramp between two levels (renamed as trigphasor).
