Public Attributes | |
uint16_t | SampleGroup |
uint32_t | Manufacturer |
Specifies the MIDI Manufacturer's Association (MMA) Manufacturer code for the sampler intended to receive this file's waveform. If no particular manufacturer is to be specified, a value of 0 should be used. | |
uint32_t | Product |
Specifies the MIDI model ID defined by the manufacturer corresponding to the Manufacturer field. If no particular manufacturer's product is to be specified, a value of 0 should be used. | |
uint32_t | SamplePeriod |
Specifies the duration of time that passes during the playback of one sample in nanoseconds (normally equal to 1 / Samplers Per Second, where Samples Per Second is the value found in the format chunk). | |
uint32_t | MIDIUnityNote |
Specifies the musical note at which the sample will be played at it's original sample rate. | |
uint32_t | FineTune |
Specifies the fraction of a semitone up from the specified MIDI unity note field. A value of 0x80000000 means 1/2 semitone (50 cents) and a value of 0x00000000 means no fine tuning between semitones. | |
smpte_format_t | SMPTEFormat |
Specifies the Society of Motion Pictures and Television E time format used in the following SMPTEOffset field. If a value of 0 is set, SMPTEOffset should also be set to 0. | |
uint32_t | SMPTEOffset |
The SMPTE Offset value specifies the time offset to be used for the synchronization / calibration to the first sample in the waveform. This value uses a format of 0xhhmmssff where hh is a signed value that specifies the number of hours (-23 to 23), mm is an unsigned value that specifies the number of minutes (0 to 59), ss is an unsigned value that specifies the number of seconds (0 to 59) and ff is an unsigned value that specifies the number of frames (0 to -1). | |
uint32_t | Loops |
Number of defined sample loops (so far only seen single loops in gig files - please report me if you encounter more!). | |
uint32_t | LoopID |
Specifies the unique ID that corresponds to one of the defined cue points in the cue point list (only if Loops > 0), as the Gigasampler format only allows one loop definition at the moment, this attribute isn't really useful for anything. | |
loop_type_t | LoopType |
The type field defines how the waveform samples will be looped (only if Loops > 0). | |
uint32_t | LoopStart |
The start value specifies the offset (in sample points) in the waveform data of the first sample to be played in the loop (only if Loops > 0). | |
uint32_t | LoopEnd |
The end value specifies the offset (in sample points) in the waveform data which represents the end of the loop (only if Loops > 0). | |
uint32_t | LoopSize |
Length of the looping area (in sample points) which is equivalent to LoopEnd - LoopStart. | |
uint32_t | LoopFraction |
The fractional value specifies a fraction of a sample at which to loop (only if Loops > 0). This allows a loop to be fine tuned at a resolution greater than one sample. A value of 0 means no fraction, a value of 0x80000000 means 1/2 of a sample length. 0xFFFFFFFF is the smallest fraction of a sample that can be represented. | |
uint32_t | LoopPlayCount |
Number of times the loop should be played (only if Loops > 0, a value of 0 = infinite). | |
bool | Compressed |

uint32_t | TruncatedBits |
For 24-bit compressed samples only: number of bits truncated during compression (0, 4 or 6). | |
bool | Dithered |
For 24-bit compressed samples only: if dithering was used during compression with bit reduction. | |
uint16_t | FormatTag |

uint32_t | SamplesPerSecond |
Sampling rate at which each channel should be played. | |

The average number of bytes per second at which the waveform data should be transferred (Playback software can estimate the buffer size using this value). | |
uint16_t | BlockAlign |
The block alignment (in bytes) of the waveform data. Playback software needs to process a multiple of BlockAlign bytes of data at a time, so the value of BlockAlign can be used for buffer alignment. | |
uint16_t | BitDepth |

unsigned long | SamplesTotal |
Reflects total number of samples (only if known sample data format is used, 0 otherwise). | |

Allocates a decompression buffer for streaming (compressed) samples with Sample::Read(). If you are using more than one streaming thread in your application you HAVE to create a decompression buffer for EACH of your streaming threads and provide it with the Sample::Read() call in order to avoid race conditions and crashes. You should free the memory occupied by the allocated buffer(s) once you don't need one of your streaming threads anymore by calling DestroyDecompressionBuffer().

Reads (uncompresses if needed) and caches the first SampleCount numbers of SamplePoints in RAM. Use ReleaseSampleData() to free the memory space if you don't need the cached samples anymore. There is no guarantee that exactly SampleCount samples will be cached; this is not an error. The size will be eventually truncated e.g. to the beginning of a frame of a compressed sample. This is done for efficiency reasons while streaming the wave by your sampler engine later. Read the Size member of the buffer_t structure that will be returned to determine the actual cached samples, but note that the size is given in bytes! You get the number of actually cached samples by dividing it by the frame size of the sample: buffer_t buf = pSample->LoadSampleData(acquired_samples);
long cachedsamples = buf.Size / pSample->FrameSize;

Loads (and uncompresses if needed) the whole sample wave into RAM. Use ReleaseSampleData() to free the memory if you don't need the cached sample data anymore. The method will add NullSamplesCount silence samples past the official buffer end (this won't affect the 'Size' member of the buffer_t structure, that means 'Size' always reflects the size of the actual sample data, the buffer might be bigger though). Silence samples past the official buffer are needed for differential algorithms that always have to take subsequent samples into account (resampling/interpolation would be an important example) and avoids memory access faults in such cases.

Sets the position within the sample (in sample points, not in bytes). Use this method and Read() if you don't want to load the sample into RAM, thus for disk streaming. Although the original Gigasampler engine doesn't allow positioning within compressed samples, I decided to implement it. Even though the Gigasampler format doesn't allow to define loops for compressed samples at the moment, positioning within compressed samples might be interesting for some sampler engines though. The only drawback about my decision is that it takes longer to load compressed gig Files on startup, because it's neccessary to scan the samples for some mandatory informations. But I think as it doesn't affect the runtime efficiency, nobody will have a problem with that.
