To meet this group, the recorder needs only capture the speaker’s voice without overloading the audio with ambient noise, as students whispering, bags being drag, etc.īased on a price range that goes up to $ 100, available resources and online popularity, the following audio recorder received the most votes: Sony ICD-UX533. Students generally do not have much money to spend, so if the goal is record only a few classes and use in academic projects, there is no need to choose a great voice recorder. There are several voice recorders on the market, and choosing between them requires a good research.Ĭheck the devices, separated by categories of use, which are among the favorites of 2018. So, depending on the style of your video, only the recorder on top of the camera may be sufficient, eliminating the cost of purchasing a microphone.
#Best recorder for class lectures professional#
The answer to this question depends on what you want to record and how often you perform this activity.įor 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.īut 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.Īnother advantage of audio recorders is that they usually come with integrated microphones. 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. The difference between the two types of recording is the depth. This means that when you listen to a track with headphones, you hear the same sound on both sides.ĭevices that record in stereo have two microphones. Mono recordings are made on a track, usually with a microphone. Handheld digital recorders either record in mono or stereo.
Smartphones record the audio in 8 bits per sample, while a higher fidelity audio recorder has depth of 24 bits. The greater the number of bits, greater the quality of the audio.įor example, the audio recorded on a CD has a depth of 16-bits per sample, which is the same as most voice recorders. The bit depth is a measure of the bits information in each sample. 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.
Most digital voice recorders sample audio with a rate of 44.1 kHz or 48 kHz. The higher the sampling rate, there will be less loss in the digital representation of the sound.
The sampling rate is the number of times per second that the audio is recorded. 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.Īudio fidelity depends in large part of the sampling rate, bit depth, and if the audio recorder is mono or stereo. This is due to a number of features, which give them unique characteristics, such as the capture of high-fidelity audio. What are the main features of an audio recorderĭigital voice recorders are capable of capturing and recording sounds with greater accuracy, fidelity and quality. Audio Recorder is a device for recording classes, lectures, conversations and other sounds.ĭespite being quite used, you may be wondering, with smartphones capable of performing this function, why invest in an exclusive device to record audio?
