Audio recorder: what are the best digital voice recorders for your business
Audio Recorder is a device for recording classes, lectures, conversations and other sounds.
Despite being quite used, you may be wondering, with smartphones capable of performing this function, why invest in an exclusive device to record audio?
What are the main features of an audio recorder
Digital voice recorders are capable of capturing and recording sounds with greater accuracy, fidelity and quality.
This is due to a number of features, which give them unique characteristics, such as the capture of high-fidelity audio.
The hi-fi stereos use the minimalist concept, where it is believed that the fewer stages there are between the sound captured, recorded, reproduced and amplified, it will have less interference and greater fidelity.
Audio fidelity depends in large part of the sampling rate, bit depth, and if the audio recorder is mono or stereo.
The sampling rate is the number of times per second that the audio is recorded.
The higher the sampling rate, there will be less loss in the digital representation of the sound.
Most digital voice recorders sample audio with a rate of 44.1 kHz or 48 kHz. The most powerful recorders sample as high as 96 kHz, however, humans can not process higher sampling rates than 50kHz in a meaningful way, which makes 96 kHz overkill in most situations.
The bit depth is a measure of the bits information in each sample. The greater the number of bits, greater the quality of the audio.
For example, the audio recorded on a CD has a depth of 16-bits per sample, which is the same as most voice recorders.
Smartphones record the audio in 8 bits per sample, while a higher fidelity audio recorder has depth of 24 bits.
Mono or Stereo
Handheld digital recorders either record in mono or stereo.
Mono recordings are made on a track, usually with a microphone. This means that when you listen to a track with headphones, you hear the same sound on both sides.
Devices that record in stereo have two microphones. The difference between the two types of recording is the depth.
The stereo sound resembles reality more, because it’s like our ears are designed to hear, similar to how two eyes reach a depth that just one can not.
Why invest in an audio recorder
The answer to this question depends on what you want to record and how often you perform this activity.
For example, if you need an audio recorder only to do informal records such as school work or a hobby, the smartphone is perfectly able to meet your needs.
But if you need to record audio on a daily basis, with professional aim, than you need the best quality audio and features offered by a digital voice recorder.
