Typedef OMX_AUDIO_CODINGTYPE

typedef enum OMX_AUDIO_CODINGTYPEOMX_AUDIO_CODINGTYPE

Enumeration used to define the possible audio codings. If "OMX_AUDIO_CodingUnused" is selected, the coding selection must be done in a vendor specific way. Since this is for an audio processing element this enum is relevant. However, for another type of component other enums would be in this area.

Typedef OMX_AUDIO_PORTDEFINITIONTYPE

typedef struct OMX_AUDIO_PORTDEFINITIONTYPEOMX_AUDIO_PORTDEFINITIONTYPE

The PortDefinition structure is used to define all of the parameters necessary for the compliant component to setup an input or an output audio path. If additional information is needed to define the parameters of the port (such as frequency), additional structures must be sent such as the OMX_AUDIO_PARAM_PCMMODETYPE structure to supply the extra parameters for the port.

typedef struct OMX_AUDIO_CONFIG_MIDIMETAEVENTTYPEOMX_AUDIO_CONFIG_MIDIMETAEVENTTYPE

MIDI Meta Event structure one per Meta Event. MIDI Meta Events are like audio metadata, except that they are interspersed with the MIDI content throughout the file and are not localized in the header. As such, it is necessary to retrieve information about these Meta Events from the engine, as it encounters these Meta Events within the MIDI content. For example, SMF files can have up to 14 types of MIDI Meta Events (copyright, author, default tempo, etc.) scattered throughout the file.

Typedef OMX_AUDIO_CONFIG_EQUALIZERTYPE

typedef struct OMX_AUDIO_CONFIG_EQUALIZERTYPEOMX_AUDIO_CONFIG_EQUALIZERTYPE

Typedef OMX_AUDIO_STEREOWIDENINGTYPE

typedef enum OMX_AUDIO_STEREOWIDENINGTYPEOMX_AUDIO_STEREOWIDENINGTYPE

Typedef OMX_AUDIO_CONFIG_STEREOWIDENINGTYPE

typedef struct OMX_AUDIO_CONFIG_STEREOWIDENINGTYPEOMX_AUDIO_CONFIG_STEREOWIDENINGTYPE

Typedef OMX_AUDIO_CONFIG_CHORUSTYPE

typedef struct OMX_AUDIO_CONFIG_CHORUSTYPEOMX_AUDIO_CONFIG_CHORUSTYPE

The chorus effect (or ``choralizer'') is any signal processor which makes one sound source (such as a voice) sound like many such sources singing (or playing) in unison. Since performance in unison is never exact, chorus effects simulate this by making independently modified copies of the input signal. Modifications may include (1) delay, (2) frequency shift, and (3) amplitude modulation.

Typedef OMX_AUDIO_CONFIG_REVERBERATIONTYPE

typedef struct OMX_AUDIO_CONFIG_REVERBERATIONTYPEOMX_AUDIO_CONFIG_REVERBERATIONTYPE

Reverberation is part of the reflected sound that follows the early reflections. In a typical room, this consists of a dense succession of echoes whose energy decays exponentially. The reverberation effect structure as defined here includes both (early) reflections as well as (late) reverberations.
