Selected as the mandatory audio codec for DRM +(Digital Radio Mondiale), Ex-HEAAC bridges the gap between speech and +audio coding, and provides consistent high quality audio for all signal +types, such as speech, music or mixed content. + +Another important feature is the codec’s coding efficiency. The audio +codec produces excellent sound for both music and speech, delivering +high quality performance at bit rates starting as low as 6 kbit/s for +mono and 12 kbit/s for stereo services. Thus Ex-HEAAC streaming apps and +streaming radio players may switch to very low bit rate streams and +offer a continuous playback even while the network is congested. Once +more bandwidth becomes available on the network again, the Ex-HEAAC +client can request a higher bitrate version and seamless switch over +the full range of bitrates. Audio bitrate that’s being saved due to the +improved coding efficiency can be used to improve video quality. Ex-HEAAC +supports AAC and HEAAC v2 as well. + +AAC is a popular audio coding technique recommended by MPEG committee. +The codec handles audio signals sampled in the range of 8 kHz to 96 +kHz. It operates on a frame of 1024 samples. The bit-rates supported +are in the range of 8 kbps to 576 kbps per channel. + +SBR and PS are the tools used in combination with the AAC general audio +codec resulting in HEAAC v2 (also known as Enhanced AAC Plus). It +provides significant increase in coding gain. In SBR, the high-band, +i.e. the high frequency part of the spectrum is replicated using the +low-band. In PS, channel redundancy is exploited and parameters are +extracted from a down-mixed channel.The bit-rate is by far below the +bit-rate required when using conventional AAC coding. This translates +into better quality at lower bit-rates. + + +# Introduction to Ex-HEAAC Decoder APIs + +## Files to be included are +* [`ixheaacd_apicmd_standards.h`](decoder/ixheaacd_apicmd_standards.h) +* [`ixheaacd_type_def.h`](decoder/ixheaacd_type_def.h) +* [`ixheaacd_memory_standards.h`](decoder/ixheaacd_memory_standards.h) +* [`ixheaacd_error_standards.h`](decoder/ixheaacd_error_standards.h) +* [`ixheaacd_error_handler.h`](decoder/ixheaacd_error_handler.h) +* [`ixheaacd_aac_config.h`](decoder/ixheaacd_aac_config.h) + +## Decoder APIs + +A single API is used to get and set configurations and execute the decode thread, based on command index passed. +* ia_xheaacd_dec_api + +| **API Command** | **API Sub Command** | **Description** | +|------|------|------| +|IA_API_CMD_GET_LIB_ID_STRINGS | IA_CMD_TYPE_LIB_NAME | Gets the decoder library name | +|IA_API_CMD_GET_LIB_ID_STRINGS | IA_CMD_TYPE_LIB_VERSION | Gets the decoder version | +|IA_API_CMD_GET_API_SIZE | 0 | Gets the memory requirements size of the API | +|IA_API_CMD_INIT | IA_CMD_TYPE_INIT_API_PRE_CONFIG_PARAMS | Sets the configuration parameters of the Ex-HEAAC v2 Decoder to default values | +|IA_API_CMD_INIT | IA_CMD_TYPE_INIT_API_POST_CONFIG_PARAMS | Sets the attributes(size, priority, alignment) of all memory types required by the application onto the memory structure | +|IA_API_CMD_SET_CONFIG_PARAM | IA_ENHAACPLUS_DEC_CONFIG_PARAM_SAMP_FREQ | Sets the core AAC sampling frequency for RAW header decoding | +|IA_API_CMD_SET_CONFIG_PARAM | IA_ENHAACPLUS_DEC_CONFIG_PCM_WDSZ | Sets the bit width of the output pcm samples.The value has to be 16 | +|IA_API_CMD_SET_CONFIG_PARAM | IA_ENHAACPLUS_DEC_CONFIG_PARAM_DOWNMIX | Sets the parameter whether the output needs to be down-mix to mono(1) or not(0) | +|IA_API_CMD_SET_CONFIG_PARAM | IA_ENHAACPLUS_DEC_CONFIG_PARAM_TOSTEREO | Sets the flag to disable interleave mono to stereo | +|IA_API_CMD_SET_CONFIG_PARAM | IA_ENHAACPLUS_DEC_CONFIG_PARAM_DSAMPLE | Sets the parameter whether the output needs to be downsampled(1) or not(0).This is valid only for Ex-HEAAC v2 build | +|IA_API_CMD_SET_CONFIG_PARAM | IA_ENHAACPLUS_DEC_CONFIG_FRAMEOK | Sets the flag to 0 or 1 to indicate whether the current frame is valid(1) or not(0) | +|IA_API_CMD_SET_CONFIG_PARAM | IA_ENHAACPLUS_DEC_CONFIG_ISMP4 | Sets the flag to 0 or 1 to indicate whether given test vector is an mp4 file or not | +|IA_API_CMD_SET_CONFIG_PARAM | IA_ENHAACPLUS_DEC_CONFIG_PARAM_DISABLE_SYNC | Sets the flag of ADTS syncing or not ADTS syncing as 0 or 1 | +|IA_API_CMD_SET_CONFIG_PARAM | IA_ENHAACPLUS_DEC_CONFIG_PARAM_AUTO_SBR_UPSAMPLE | Sets the parameter auto SBR upsample to 0 or 1.Used in case of stream changing from SBR present to SBR not present.This is valid only for Ex-HEAAC v2 build | +|IA_API_CMD_SET_CONFIG_PARAM | IA_ENHAACPLUS_DEC_CONFIG_PARAM_MAX_CHANNEL | Sets the maximum number of channels present.Its maximum value is 2 for stereo library and 8 for multichannel library | +|IA_API_CMD_SET_CONFIG_PARAM | IA_ENHAACPLUS_DEC_CONFIG_PARAM_COUP_CHANNEL | Sets the number of coupling channels to be used for coupling.It can take values from 0 to 16.This command is supported only if the library has multichannel support | +|IA_API_CMD_SET_CONFIG_PARAM | IA_ENHAACPLUS_DEC_CONFIG_PARAM_DOWNMIX_STEREO | Sets the flag of downmixing n number of channels to stereo.Can be 0 or 1.
