Definitions
- the invention relates to a method for improving the sound quality of an audio file in an audio device by changing an audio signal by means of at least one
- the invention relates to a device for carrying out the method.
- effect devices such as equalizers, compressors, limiters, as well as reverberation and echo devices are used.
- a compressor / limiter for example, is a limiter that exceeds a
- Peak level prevents to prevent oversteer. Also, they are important as volume / loudness regulators of instrument groups / vocals or speech. For this, values of the parameters Channel Fader, Threshold, Attack (if available), Release, and Output Level are set. Equalizers, for example, are used to correct, equalize or otherwise influence the sound pattern and consist of several filters with which the whole
- Audio frequency range of the audio signal can be edited. This happens, for example, via the specific setting of frequencies and the filter quality.
- Effect devices are thus always associated with specific settings to influence or improve the sound quality of audio signals, including an audio file.
- the overall sound of the audio playing device is adjusted, i. the selected effect device settings should apply to any audio played back through the audio device.
- the respective terminal device which can be set by the consumer or user, is positioned by the manufacturer of the audio device in the main audio channel path of the relevant device. It does not matter whether it is an audio-playing device with one, two or more channels. To the consumer or user of the audio device a broader
- Compressor / Limiter for example, values of parameters such as channel fader, Threshold, Attack, Release, and Output Level are already set. Some of these presets are already preprogrammed, such as Music, Movie, or Game settings, so they're supposed to stand for a specific sound, while others are free to create and save, called user presets. If the consumer or user wishes to switch between the various settings, he must select the effect device and manually change the setting, either by activating a stored preset or manually creating a new setting.
- the method according to the invention is characterized by the following steps: a) assignment of the audio file to metadata; b) comparison of metadata with files storing settings of the effects device; c) assignment of the metadata to a file from step b) and d) loading of the file from step c) and activation of the effect device, wherein the effect device with values from the file in step c) is set.
- the core idea of the invention is, if possible for each audio file to achieve an individual sound adaptation by first capturing an audio file using metadata and
- Metadata is descriptive data about media files, such as audio and video files. They are used to describe the contents of these files (e.g., composer, track, genre) or summaries of various
- Metadata are either changeable and unchangeable components of a media file or even of
- Media files detached descriptions which are managed for example in metadatabases. They are also linked to specific media files, but are external and not within the media file itself.
- media-file internal for example ID3 tag
- media-file-external freely selectable metadata catalogs
- Settings of the effects device may also be stored in the storage medium, in the audio files are stored to which metafiles are assigned and / or can be assigned.
- the method according to the invention solves the problem of the previously absent individual sound adaptation.
- the advantage of the invention is that it is now possible for the first time to provide in each case individually played audio events with the optimal effect units set for them.
- the consumer or user does not have to intervene on his own, but comes in the automatically optimized on the audio-playing device and / or his listening environment enjoyment of his audio events.
- a distribution of automated and manually adjustable effect devices it is also possible to allow the consumer or user of an audio device to interfere with the sound, so he can further customize it as needed.
- the method according to the invention becomes more and more precise, the more information, i. the more metadata about the audio files to be played is available and can be evaluated.
- the inventive method the individual optimization of sound events of all epochs, genres and styles can be done.
- audio events of different epochs, which are played in succession in the mix, sound homogeneous, since, for example, lower-quality sound qualities of older recordings can be adapted individually to the contemporary sound by the method according to the invention.
- An advantageous development of the invention provides that the metadata be stored in the audio file.
- a practicable variant of the invention provides that the metadata be stored in an external database.
- the latter variant of the invention has the advantage that it can be used on large providers of metadata and their repertoire of musical pieces.
- the files from step b) are stored in a database of the audio device or in a cloud.
- the set effect units include.
- the database can also be an external database, ie it can be located outside of the audio device. Large stocks of files in turn have the advantage that a further differentiation of set effect devices and thus the audio files is made,
- Effect device changed audio signal is routed to audio outputs of the device.
- An apparatus for carrying out the method is subject-matter of claim 7, wherein it comprises:
- the device has audio outputs and / or audio inputs.
- a computer program implemented in an apparatus according to any one of claims 7 to 10 is subject matter of claim 13, wherein the computer program includes an algorithm executed by a processor of the apparatus, the algorithm comprising the method according to one of claims 1 to 6 processed.
- the computer program can also be in the form of a media player.
- 1 is a block diagram with several effect units as a unit
- FIG. 2 shows the method according to the invention shown in a block diagram
- FIG. 3 shows in a block diagram the components of a container format according to FIG.
- Fig. 4 is a flowchart additionally shown in a block diagram in a
- FIG. 12 is a block diagram of the components of a computer program in FIG.
- Shape of a media player according to the invention is a shape of a media player according to the invention.
- Figure 1 shows in a block diagram a number of effect devices 1, 2, 3, 4, 5, 6, 7, which are interconnected and together via an audio input 8 and a
- Audio output 9 feature are used to change the audio signal of an audio file not shown in FIG.
- the effect units 1, 2, 3, 4, 5, 6, 7 are a "bypass” for activating / deactivating the entire unit, an “equalizer” for adjusting different frequency bands, a “speech enhancer” for highlighting voices, eg within movies, a “bass / treble boost” to raise or lower freely adjustable bass and treble frequencies, a “leveler” to automatically adjust the volume level over time, a “stereo spread” to expand the sound and "Limiter” to intercept peak levels at the end of the signal chain to prevent overmodulation.
- FIG. 2 shows the method according to the invention, in which metadata stored in an audio file, not shown in FIG. 2, via at least one data line 12, 23 is supplied to the control module 10, which has a microcontroller.
- audio signals of the audio file which is stored in a storage medium (not shown in FIG. 2), pass via a line 11 into an effects device 2, which is present in the form of an equalizer in the embodiment of the invention shown in FIG.
- an effects device 2 which is present in the form of an equalizer in the embodiment of the invention shown in FIG.
- a composite of effect devices, as shown in FIG. 1 can also be used.
- the audio signal processed by the effect device 2 arrives at the audio output 9.
- Both audio and metadata, ie data with accompanying information about the currently playing audio event are processed in the control module 10.
- the control module 10 assigns specific settings of the effect device 2 via the control line 13 to certain metadata and activates them as soon as the audio event begins to play, since the metadata processed by the control module 10 is at the beginning of the audio file or not in FIG external metadata bank associated with the currently playing audio file.
- Metadata is descriptive data about media files, such as audio and video files. They are used to describe the contents of these files (eg composer, length, genre) or to describe summaries of various file formats called container formats.
- Figure 3 shows a container format AVI (Audio Video Interleave), which is provided with the reference numeral 14.
- the metadata describes here as "header data" 15 the synchronized combination of a video 16 with an audio file 17.
- the consumer or user activates only the higher-level AVI file, which carries image and sound together in its container and sound without complication to a jointly controlled file to combine.
- the control module 10 assigns, as also illustrated in Figure 4, metadata certain predetermined settings of the effects device 2, which are stored under metadata identical names in a file 21 in a storage medium and can be retrieved.
- the control module 10 converts metadata into control data for the effect device 2 from a freely configurable number and type of metadata, which enter the control module 10 via at least one data line 12, 22.
- the control module 10 recognizes in the first function section 18 which combination of letters, numbers and characters is the currently read metadata. After recognizing the received metadata, these are compared with the data contained in the file 21 records and assigned in the function section 19.
- the existing in a media or audio file audio data such as LPCM (Linear Pulse Code Modulation) in the audio format AIFF (Audio Interchange File Format) are fed directly to the effects device 2 and edited there.
- LPCM Linear Pulse Code Modulation
- AIFF Audio Interchange File Format
- the effect device 2 may also have a freely configurable number and type of sound modules, all of which are preconfigurable via manual or automatic presets. These default and stored under individual combinations of letters, numbers and characters adjustments are then activated via the control module 10, so that the effect device 2 loads the activated preset and modulates the sound according to the activated preset.
- the connected effect device as shown in FIG.
- the 5 may also contain so-called master sound modules which adapt the entire sound system to all automatable sound modules.
- This master parameter which is composed of the additional equalizer 2b and the intensity 2a, makes it possible to adapt the overall sound system to special events, such as listening via headphones as opposed to listening in the car.
- the method according to the invention can be easily adapted and thereby used to a maximum of flexibility.
- control module 10 does not have an undetermined number of effect devices 2, 2 a associated with an unspecified number of audio data sources fixed number of metadata sources, controls ( Figure 6).
- an unidentified number of control modules 10, 10a controls an effects device 2 having an undefined number of audio data sources based on an undefined number of metadata sources (FIG. 7).
- an undetermined number of control modules 10, 10a control effects devices 2, 2a with an unspecified number of audio data sources based on an undefined number of metadata sources. ( Figure 8).
- the metadata source 24 of the control module 10 is a media file with integrated metadata (FIG. 9).
- the metadata source of the control module 10 is a media-external file, ie separate from the media file 25 (audio file) (FIG. 10).
- the metadata sources of the control module 10 are an external file 30 and the audio file 31.
- the metadata from the audio file 31 is supplied via the line 26 to the control module 10 ( Figure 11).
- Figure 12 shows a computer program 27.
- the control module 10 recognizes the metadata of the media file activated in the playlist 28 and / or the metadata of external metadata banks associated with the media file 29. After recognition, the control module is the same 10 the metadata found with the records contained in the file 21.
- control module 10 If the control module 10 is able to assign a control data record located in the file 21 and / or an external metadata bank 29 to the media file activated in the playlist 28, it sends the control command in the file to the effect device, which changes according to the control data contained in the control file , Finally, the audio outputs 9 of the effects device 2 are led out of the media player present as a present computer program 27, so that they can be connected to amplifiers / loudspeakers or further processed.
