Tables (or arrays)

The default table. It's rendered to (-1) in the Csound.

nsamp — Returns the number of samples loaded into a stored function table number.

nsamp(x) (init-rate args only)

csound doc: http://www.csounds.com/manual/html/nsamp.html

Returns a length of the table.

Returns the sample rate for a table that stores wav files

Returns the number of channels for a table that stores wav files

Returns the base frequency for a table that stores wav files

Table size fidelity (how many points in the table by default).

Sets different table size for different GEN-routines.

fineFi n ps 

where

• n is the default value for table size (size is a n power of 2) for all gen routines that are not listed in the next argument ps.
• ps is a list of pairs (genRoutineId, tableSizeDegreeOf2) that sets the given table size for a given GEN-routine.

with this function we can set lower table sizes for tables that are usually used in the envelopes.

Sets the same table size for all tables.

coarseFi n

where n is a degree of 2. For example, n = 10 sets size to 1024 points for all tables by default.

Table contains all provided values (table is extended to contain all values and to be of the power of 2 or the power of two plus one). (by default it skips normalization).

Creates a new table. The Tab could be used while the instrument is playing. When the instrument is retriggered the new tab is allocated.

newTab size

Creates a new global table. It's generated only once. It's persisted between instrument calls.

newGlobalTab identifier size

Calculates the number of samples needed to store the given amount of seconds. It multiplies the value by the current sample rate.

Calculates the closest power of two value for a given size.

Calculates the closest power of two value in samples for a given size in seconds.

Loads wav or aiff file to table

wavs fileName skipTime channel

skipTime specifies from what second it should read the file.

with channel argument we can read left, right or both channels.

Loads mp3 file to table:

mp3s fileName skipTime format

skipTime specifies from what second it should read the file.

format is: 1 - for mono files, 2 - for stereo files, 3 - for left channel of stereo file, 4 for right channel of stereo file

Series of harmonic partials:

sine = sines [1]

saw = sines $ fmap (1 / ) [1 .. 10]

square = sines $ fmap (1 / ) [1, 3 .. 11]

triangle = sines $ zipWith (\a b -> a / (b ** 2)) (cycle [1, -1]) [1, 3 .. 11]

Specifies series of possibly inharmonic partials.

Just like sines3 but phases are set to zero.

Just like sines2 but partial strength is set to one.

Specifies series of possibly inharmonic partials with direct current.

Generates values similar to the opcode buzz.

buzzes numberOfHarmonics [lowestHarmonic, coefficientOfAttenuation]

With buzzes n [l, r] you get n harmonics from l that are attenuated by the factor of r on each step.

splines [a, n1, b, n2, c, ...]

Creates a table from a starting value to an ending value.

startEnds [val1, dur1, type1, val2, dur2, type2, val3, ... typeX, valN]

• val1, val2 ... -- end points of the segments
• dur1, dur2 ... -- durations of the segments
• type1, type2 ... -- if 0, a straight line is produced. If non-zero, then it creates the following curve, for dur steps:

beg + (end - beg) * (1 - exp( i*type)) / (1 - exp(type * dur))

• beg, end - end points of the segment
• dur - duration of the segment

Creates tables for the padsynth algorithm (described at http://www.paulnasca.com/algorithms-created-by-me). The table size should be very big the default is 18 power of 2.

csound docs: http://csound.github.io/docs/manual/GENpadsynth.html

Padsynth parameters.

see for details: http://csound.github.io/docs/manual/GENpadsynth.html

Specs for padsynth algorithm:

defPadsynthSpec partialBandwidth harmonics

• partialBandwidth -- bandwidth of the first partial.
• harmonics -- the list of amplitudes for harmonics.

Creates a table of doubles (It's f-table in Csound). Arguments are:

• identificator of the GEN routine
• GEN routine arguments

All tables are created at 0 and memory is never released.

Skips normalization (sets table size to negative value)

Force normalization (sets table size to positive value). Might be useful to restore normalization for table doubles.

Sets an absolute size value. As you can do it in the Csound files.

Sets the relative size value. You can set the base value in the options (see tabResolution at CsdOptions, with tabResolution you can easily change table sizes for all your tables). Here zero means the base value. 1 is the base value multiplied by 2, 2 is the base value multiplied by 4 and so on. Negative values mean division by the specified degree.

Adds guard point to the table size (details of the interpolation schemes: you do need guard point if your intention is to read the table once but you don't need the guard point if you read table in many cycles, the guard point is the the first point of your table).

Shortcut for guardPoint.

Writes tables in sequential locations.

This opcode writes to a table in sequential locations to and from an a-rate variable. Some thought is required before using it. It has at least two major, and quite different, applications which are discussed below.
