   CodedColor: Provides less image editing functionality than Photoshop but included many useful tools like image viewing, creation of web albums, organization of pictures with keywords and annotations. Adobe Photoshop Elements: Comes as part of some scanner and digital camera software. Described as for the serious hobbyist, it is a scaled down ...

3. Pitch correction - Wikipedia

   en.wikipedia.org/wiki/Pitch_correction

   Pitch correction is an electronic effects unit or audio software that changes the intonation (highness or lowness in pitch) of an audio signal so that all pitches will be notes from the equally tempered system (i.e., like the pitches on a piano). Pitch correction devices do this without affecting other aspects of its sound.

4. Audio editing software - Wikipedia

   en.wikipedia.org/wiki/Audio_editing_software

   Audio editing software typically offer the following features: The ability to import and export various audio file formats for editing. Record audio from one or more inputs and store recordings in the computer's memory as digital audio. Edit the start time, stop time, and duration of any sound on the audio timeline.

5. Sound quality - Wikipedia

   en.wikipedia.org/wiki/Sound_quality

   Sound quality is typically an assessment of the accuracy, fidelity, or intelligibility of audio output from an electronic device. Quality can be measured objectively, such as when tools are used to gauge the accuracy with which the device reproduces an original sound; or it can be measured subjectively, such as when human listeners respond to ...

6. Audio time stretching and pitch scaling - Wikipedia

   en.wikipedia.org/wiki/Audio_time_stretching_and...

   The simplest way to change the duration or pitch of an audio recording is to change the playback speed. For a digital audio recording, this can be accomplished through sample rate conversion. When using this method, the frequencies in the recording are always scaled at the same ratio as the speed, transposing its perceived pitch up or down in ...

7. Equalization (audio) - Wikipedia

   en.wikipedia.org/wiki/Equalization_(audio)

   Later the concept was applied in audio engineering to adjust the frequency response in recording, reproduction, and live sound reinforcement systems. Sound engineers correct the frequency response of a sound system so that the frequency balance of the music as heard through speakers better matches the original performance picked up by a microphone.

8. Noise reduction - Wikipedia

   en.wikipedia.org/wiki/Noise_reduction

   Noise reduction techniques exist for audio and images. Noise reduction algorithms may distort the signal to some degree. Noise rejection is the ability of a circuit to isolate an undesired signal component from the desired signal component, as with common-mode rejection ratio.

9. High-resolution audio - Wikipedia

   en.wikipedia.org/wiki/High-resolution_audio

   High-resolution audio (high-definition audio or HD audio) is a term for audio files with greater than 44.1 kHz sample rate or higher than 16-bit audio bit depth. It commonly refers to 96 or 192 kHz sample rates. However, 44.1 kHz/24-bit, 48 kHz/24-bit and 88.2 kHz/24-bit recordings also exist that are labeled HD audio.
