Statics§

speex_mode_list
List of all modes available
speex_nb_mode
Default narrowband mode
speex_uwb_mode
Default “ultra-wideband” mode
speex_wb_mode
Default wideband mode

Functions§

speex_bits_advance
Advances the position of the “bit cursor” in the stream
speex_bits_destroy
Frees all resources associated to a SpeexBits struct. Right now this does nothing since no resources are allocated, but this could change in the future.
speex_bits_init
Initializes and allocates resources for a SpeexBits struct
speex_bits_init_buffer
Initializes SpeexBits struct using a pre-allocated buffer
speex_bits_insert_terminator
Insert a terminator so that the data can be sent as a packet while auto-detecting the number of frames in each packet
speex_bits_nbytes
Returns the number of bytes in the bit-stream, including the last one even if it is not “full”
speex_bits_pack
Append bits to the bit-stream @param bits Bit-stream to operate on @param data Value to append as integer @param nbBits number of bits to consider in “data”
speex_bits_peek
Get the value of the next bit in the stream, without modifying the “cursor” position
speex_bits_peek_unsigned
Same as speex_bits_unpack_unsigned, but without modifying the cursor position
speex_bits_read_from
Initializes the bit-stream from the data in an area of memory
speex_bits_read_whole_bytes
Append bytes to the bit-stream
speex_bits_remaining
Returns the number of bits remaining to be read in a stream
speex_bits_reset
Resets bits to initial value (just after initialization, erasing content)
speex_bits_rewind
Rewind the bit-stream to the beginning (ready for read) without erasing the content
speex_bits_set_bit_buffer
Sets the bits in a SpeexBits struct to use data from an existing buffer (for decoding without copying data)
speex_bits_unpack_signed
Interpret the next bits in the bit-stream as a signed integer
speex_bits_unpack_unsigned
Interpret the next bits in the bit-stream as an unsigned integer
speex_bits_write
Write the content of a bit-stream to an area of memory
speex_bits_write_whole_bytes
Like speex_bits_write, but writes only the complete bytes in the stream. Also removes the written bytes from the stream
speex_decode
Uses an existing decoder state to decode one frame of speech from bit-stream bits. The output speech is saved written to out.
speex_decode_int
Uses an existing decoder state to decode one frame of speech from bit-stream bits. The output speech is saved written to out.
speex_decode_stereo
Transforms a mono frame into a stereo frame using intensity stereo info
speex_decode_stereo_int
Transforms a mono frame into a stereo frame using intensity stereo info
speex_decoder_ctl
Used like the ioctl function to control the encoder parameters
speex_decoder_destroy
Frees all resources associated to an existing decoder state.
speex_decoder_init
Returns a handle to a newly created decoder state structure. For now, the mode argument can be &nb_mode or &wb_mode . In the future, more modes may be added. Note that for now if you have more than one channels to decode, you need one state per channel.
speex_default_user_handler
Default handler for user-defined requests: in this case, just ignore
speex_encode
Uses an existing encoder state to encode one frame of speech pointed to by “in”. The encoded bit-stream is saved in “bits”. @param state Encoder state @param in Frame that will be encoded with a +-2^15 range. This data MAY be overwritten by the encoder and should be considered uninitialised after the call. @param bits Bit-stream where the data will be written @return 0 if frame needs not be transmitted (DTX only), 1 otherwise
speex_encode_int
Uses an existing encoder state to encode one frame of speech pointed to by “in”. The encoded bit-stream is saved in “bits”. @param state Encoder state @param in Frame that will be encoded with a +-2^15 range @param bits Bit-stream where the data will be written @return 0 if frame needs not be transmitted (DTX only), 1 otherwise
speex_encode_stereo
Transforms a stereo frame into a mono frame and stores intensity stereo info in ‘bits’
speex_encode_stereo_int
Transforms a stereo frame into a mono frame and stores intensity stereo info in ‘bits’
speex_encoder_ctl
Used like the ioctl function to control the encoder parameters
speex_encoder_destroy
Frees all resources associated to an existing Speex encoder state. @param state Encoder state to be destroyed
speex_encoder_init
Returns a handle to a newly created Speex encoder state structure. For now, the “mode” argument can be &nb_mode or &wb_mode . In the future, more modes may be added. Note that for now if you have more than one channels to encode, you need one state per channel.
speex_header_free
Frees the memory allocated by either speex_header_to_packet() or speex_packet_to_header()
speex_header_to_packet
Creates the header packet from the header itself (mostly involves endianness conversion)
speex_inband_handler
Handle in-band request
speex_init_header
Initializes a SpeexHeader using basic information
speex_lib_ctl
Functions for controlling the behavior of libspeex @param request ioctl-type request (one of the SPEEX_LIB_* macros) @param ptr Data exchanged to-from function @return 0 if no error, -1 if request in unknown, -2 for invalid parameter
speex_lib_get_mode
Obtain one of the modes available
speex_mode_query
Query function for mode information
speex_packet_to_header
Creates a SpeexHeader from a packet
speex_std_char_handler
Standard handler for in-band characters (write to stderr)
speex_std_enh_request_handler
Standard handler for enhancer request (Turn enhancer on/off, no questions asked)
speex_std_high_mode_request_handler
Standard handler for high mode request (change high mode, no questions asked)
speex_std_low_mode_request_handler
Standard handler for low mode request (change low mode, no questions asked)
speex_std_mode_request_handler
Standard handler for mode request (change mode, no questions asked)
speex_std_stereo_request_handler
Callback handler for intensity stereo info
speex_std_vbr_quality_request_handler
Standard handler for VBR quality request (Set VBR quality, no questions asked)
speex_std_vbr_request_handler
Standard handler for VBR request (Set VBR, no questions asked)
speex_stereo_state_destroy
Destroy a stereo stereo state
speex_stereo_state_init
Initialise/create a stereo stereo state
speex_stereo_state_reset
Reset/re-initialise an already allocated stereo state
