Clarified filters and hashers on README
2022-07-29 10:57:50 +00:00
## Filters
| Filter | Native Sample Format | Notes |
|:-------------:|:---------------------:|:---------------------------------------------------------------------------------------------------------------------------:|
| Resample | `float32` | Changes input source sample rate to a different sample rate.<br/>If source sample rate equals `sampleRate`, returns source. |
| Source Format | `float32 int16 int32` | Changes input source to a different format. |
| Buffer | `float32 int16 int32` | Makes output source a buffered channel of the specified size. |
| Block Size | `float32 int16 int32` | Adjusts input source blocks to a normalized block size. |
| Real Time | `float32 int16 int32` | Outputs enough samples per second equal to the source sample rate. |
| Volume | `float32 int16 int32` | Adjusts volume of all samples equally.<br/>If `adjustement` equals `1.0`, returns source. |
| Stereo | `float32 int16 int32` | Makes input stereo.<br/>If source channels equals `2`, returns source. |
| Mono | `float32 int16 int32` | Makes input mono.<br/>If source channels equals `1`, returns source. |
| ReplayGain | `float32 int16 int32` | Creates a Volume filter with the specified ReplayGain parameters. |
| Normalization | `float32` | Automatically adjusts volume according to short term audio loudness. |
### Filter Chain
Allows chaining different filters together where one's output is the next one input.
## Hashers
Several audio Analyzer hashers are implemented. List of current ones:
* CRC32
* SHA256
* SHA1
* MD5
* AccurateRipV1
* AccurateRipV1 (Start mode)
* AccurateRipV2
* AccurateRipV2 (Start mode)

## Build tags
Several Golang build tags exist to change which features are included in the project.
Added support for building using CGO_ENABLED=0 with limited codec and performance
2022-05-20 15:23:50 +00:00
### CGO_ENABLED=0
This tag disables CGO support, and disables any formats/codecs that require it. Some other features will degrade or be less performant, or alternative decoders be used.
Additionally, libebur128 (used for normalization) will be disabled.
Some tests cannot be completed in this mode.
#### Codecs supported, CGO_ENABLED=0
Use float32 native output on mp3 decoders
2022-12-01 09:32:27 +00:00
| Codec | Containers | Decoder | Sample Analyzer | Sample Format | Encoder | Notes |

| **FLAC** | [FLAC](https://xiph.org/flac/format.html) | ✅ | ✅ | `int32` | ✅* | Decoding/encoding by [flacgo](https://git.gammaspectra.live/S.O.N.G/flacgo).<br/>*Encoder only supports Verbatim / Constant frame prediction modes, offering almost no compression. |
| **TTA** | [TTA](https://www.tausoft.org/en/true_audio_codec_format/) | ✅ | ✅ | `int32` | ✅ | Decoding/encoding by [S.O.N.G/go-tta](https://git.gammaspectra.live/S.O.N.G/go-tta). |

Added support for building using CGO_ENABLED=0 with limited codec and performance
2022-05-20 15:23:50 +00:00
Improved guess package, split tests into individual files, added alternate aac encoder
2022-04-22 12:06:01 +00:00
### disable_format_[format]
This tag disables support for the specified format/codec. This does not affect packetizers.
Current implemented [format]: `aac, alac, flac, mp3, opus, tta, vorbis`. Disabling `flac` will break tests.
### disable_codec_libfdk-aac
This tag disables the [libfdk-aac](https://git.gammaspectra.live/S.O.N.G/go-fdkaac) support for decoding/encoding AAC. This is available for specific problems with the FDK license that conflicts with your needs or policy.
If this tag is enabled, yet `aac` support remains enabled, an AAC encoder (but not decoder) will be built with the [VisualOn AAC encoder](https://github.com/gen2brain/aac-go) bindings, which are vastly worse.
Added alternate go FLAC decoder
2022-05-19 15:00:06 +00:00
### disable_codec_libflac
Pure go FLAC packetizer doing minimal stream decoding, allow offseting packets. This removes the libflac / flacgo packetizers
2022-07-27 01:04:02 +00:00
This tag disables the [libFLAC](https://gitlab.xiph.org/xiph/flac) support for decoding/encoding FLAC.
Added alternate go FLAC decoder
2022-05-19 15:00:06 +00:00

2022-07-27 01:04:02 +00:00
If this tag is enabled, yet `flac` support remains enabled, [flacgo](https://git.gammaspectra.live/S.O.N.G/flacgo) FLAC decoder/encoder will be used.
Added alternate go FLAC decoder
2022-05-19 15:00:06 +00:00
Added libvorbis encoder/decoder
2022-07-28 13:01:20 +00:00
### disable_codec_libvorbis
This tag disables the [libvorbis](https://gitlab.xiph.org/xiph/vorbis) support for decoding/encoding Vorbis.
If this tag is enabled, yet `vorbis` support remains enabled, [jfreymuth/vorbis](https://github.com/jfreymuth/vorbis) via [jfreymuth/oggvorbis](https://github.com/jfreymuth/oggvorbis) Vorbis decoder will be used.
Improved guess package, split tests into individual files, added alternate aac encoder
2022-04-22 12:06:01 +00:00
### disable_codec_lame
This tag disables the [LAME](https://github.com/viert/go-lame) support for encoding MP3. This is available for specific problems with the LGPL v2 license that conflicts with your needs or policy.
MP3 decoding is not affected by this tag.
### disable_codec_tta
This tag disables the [TTA](https://git.gammaspectra.live/S.O.N.G/go-tta) support for decoding/encoding TTA. This is available for specific problems with the LGPL v3 license that conflicts with your needs or policy.
This is equivalent to `disable_format_tta`.
Disable ALAC by default due to security issues.
2022-04-22 16:18:09 +00:00
### enable_codec_libalac
This tag enables the [libalac](https://git.gammaspectra.live/S.O.N.G/go-alac) support for decoding/encoding ALAC.
This library has vast security issues, enable on your own risk. An alternate codec for decoding might be added in the future.
Added cmd/decode information on README
2023-01-29 13:00:18 +00:00
## Utilities
### `cmd/decode`
Example application that decodes files and provides some general information about the decoded streams, and produces an MD5 hash of the sample data.
Run via `$ go run git.gammaspectra.live/S.O.N.G/Kirika/cmd/decode -input "resources/samples/cYsmix - Haunted House/11. The Great Rigid Desert.flac"`
Example output:
