Description

	`f_frameSizeBytes: int;`

constructor create(rate: int = 24000; frame_size: int = 480; channels: int = 1; const libname: string = '');

Loads library and initializes the coder with specified parameters. Aborts with exception if library was not loaded.

rate: Sampling rate, from 8000 to 96000.
frame_size: Frame size is samples (per channel), must be even (and should divide on 80?)
channels: Number of channels, 1 for mono, 2 for stereo
libname: Library file name

function IOCTL(req: int; var value: int32): int;

Query and set coder parameters.

Error code

function open(): int; overload;

Initializes the coder with parameters specified upon creation or previois open().

0 if succeeded, negative value otherwise (see CELT_ error codes).

function open(rate: int; frame_size: int = 480; channels: int = 1): int; overload;

Initializes the coder with specified parameters.

rate: Sampling rate, from 32000 to 96000.
frame_size: Frame size is samples (per channel), must be even (and should divide on 80?)
channels: Number of channels, 1 for mono, 2 for stereo
libname: Library file name

0 if succeeded, negative value otherwise (see CELT_ error codes).

	`function doIOCTL(req: int; var value: int32): int; virtual; abstract;`
IOCTL the coder.

	`function doOpen(): int; virtual; abstract;`
Opens the coder.

	`function lock(timeout: tTimeout = 100): bool;`
DLL Re-entrance lock.

	`procedure BeforeDestruction(); override;`

	`procedure close();`
Releases the coder resources.

	`procedure doClose(); virtual; abstract;`
Closes the coder.

	`procedure doDataAvail(data: pointer; size: int); virtual;`
Called when encoder or decoder is ready with new portion of data.

	`procedure unlock();`
DLL Re-entrance unlock.

	`property active: bool read f_active;`
True if coder is opened

	`property frameSize: int read f_frameSize2 write setFrameSize;`
frame size in samples (per channel)

	`property lastError: int read f_lastError;`
Last error (shared for all threads!)

	`property libOK: bool read f_libOK;`
True if liblary was loaded

	`property onDataAvail: unaLibCELTcoderDataAvail read f_onDataAvail write f_onDataAvail;`
Fired for each new chunk of audio

	`property pcm_channels: int read f_channels;`
number of channels

	`property pcm_rate: int read f_rate;`
sampling rate

	`property proc: punaLibCELTAPI read getProc;`
libcelt API
